Answer:
10^2 . . . . see below for additional information or versions of the answer(s)
Step-by-step explanation:
You seem to want 10^exponent, where exponent is an even single digit, not zero.
We choose exponent = 2, so your expression is ...
10^2
__
There are several versions of expanded form. One uses exponents. In that form, the expression above is the expanded form.
Another uses multipliers of 1, 10, 100, 1000, and so on. In that form, the expression expands as ...
10^2 = 1×100
Another expanded form uses individual digits of the expanded form with others set to zero
10^2 = 100
The standard form is ...
10^2 = 100.
_____
We suppose your exponential expression might have another multiplier, such as 2.98:
exponential expression: 2.98×10^2
standard form: 298
expanded form 1: 2×10^2 + 9×10^1 +8×10^0
expanded form 2: 2×100 +9×10 +8×1
expanded form 3: 200 + 90 + 8

Write an equation of the line in point-slope form through each pair of points. (0,0) and (-4,7)
The general form of a linear equation is y - y1 = m(x - x1). The point-slope form is y = - 1.75x.
What is point-slope form?The general form of a linear equation is y - y1 = m(x - x1). It draws attention to the line's slope and one of the line's points (that is not the y-intercept).
Given: (x1, y1) = (0, 0) and (x2, y2) = (-4, 7)
The point-slope form is given by,
y - y1 = m(x - x1)
m = (y2 - y1)/(x2 - x1)
substitute the values in the above equation, we get
m = (7- 0)/(-4 - 0) = -7/4
The value of m = -7/4.
y = -1.75x
Therefore, the point-slope form is y = - 1.75x

stars in our galaxy and about 100 billion galaxies in the observable universe. Suppose every galaxy has as many stars as ours. How many stars are in the observable universe? Write in scientific notation.
The number of stars in 100 billion galaxies in scientific notation is
3 x [tex]10^{22}[/tex].
What is scientific notation?Scientific Notation is the expression of a number in the form a x [tex]10^{b}[/tex]. where a is an integer such that 1 ≤ |a| < 10 and b is an integer too.
We have,
Number of stars in our galaxy = 3 x [tex]10^{11}[/tex]
Number of galaxies in the observable universe = 100 billion.
1 billion = 1,000,000,000 = [tex]10^{9}[/tex]
Number of stars in 100 billion galaxies:
= 3 x [tex]10^{11}[/tex] x 100 x [tex]10^{9}[/tex]
= 3 x [tex]10^{11 + 2 + 9}[/tex]
= 3 x [tex]10^{22}[/tex]

When you adjust one number and change another number in the problem to make a computation easier you use ?
To make a computation easier, you adjust one number and alter another number in the problem is called compensation.
What is termed as the compensation strategy?Compensation is a multi-digit addition mental math technique that entails adjusting one of the operand to make the equation simpler to solve.
Some students might choose this strategy over left-to-right addition or even the strategy of splitting up the second number.Compensation is an effective method for making calculations easier to solve. More likely, it encourages learners to think about numbers in a variety of ways.Some examples of compensation are-
For example; 29 + 96We can alter the value of 29 to 30 by adding 1; as it is simpler to sum 30.Then, 30 + 96 = 126Now, the added value is then subtracted from obtained addition.126 - 1 = 125Hence, 29 + 96 = 125Thus, this method is used in solving with simpler form.

How to solve an equation?To solve linear equations, utilize the steps that are provided below.
Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12
⇒ 4z = 12 – 4
⇒ 4z = 8
⇒ z = 8/4
⇒ z = 2
See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

What is limit of a function how to find limit using graph?Limit : Limit is the value that a function output approaches as the input approaches to a certain value.
For any function g(x) , [tex]\lim_{x \to \22} g(x)[/tex] refers to the value that the g(x) approaches as the x approaches to 2 from either left hand side or from right hand side
From any graph we can easily see that to what value g(x)=y on the curve is approaching when the x is approaching to some value on x axis and if the graph is splitting into different functions on the value of x where x is approaching then the limit does not exist for that value of x.
For given graph h(x)
We can see value of value of function h at x=5 is 8 and value of function h at x=7 is 4
As the graph of h(x) has a hole in the graph when x=5, breaking its function into two different function on x=5 then or limit of h(x) at x=5 does not exist
As the graph of h(x) has a hole in the graph when x=7, breaking its function into two different function on x=7 then or limit of h(x) at x=7 does not exist
As the graph is not breaking at x=8or we can say that graph of g(x)is approaching to 5 as x approaches to 8 then limit of h(x) at x=8 is equal to g(1) that is 5

According to the given question.
We have a linear equation in one variable.
7(a+1)-3 a=5+4(2a-1)
As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofre, the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is given by
7(a+1) -3a = 5 + 4(2a - 1)
⇒ 7a + 7 - 3a = 5 + 8a - 4 (by distributive rule)
⇒ 4a + 7 = 1 + 8a
⇒ 7 - 1 = 8a - 4a
⇒ 6 = 4a
⇒ 6/4 = a
⇒ a = 3/2
Hence, the the solution of the linear equation in one variable 7(a+1)-3 a=5+4(2a-1) is at a = 3/2.

What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The given statement "If {x⁴=16}, then x=2" is true. This is because we solve the equation x⁴=16 for the value of x as shown below, then the value of x will be 2, as shown below.
x⁴ = 16
x⁴ = 2 × 2 × 2 × 2
x × x × x × x = 2 × 2 × 2 × 2
x = 2
As it is seen that the value of x is 2. Although, the given statement may be false if the value of x is -2 because still the value of x⁴ = 16, but the only two options available are true and false. Thus, we can conclude that the given statement is true.
