Answers

We have been given the expression 2^5/8=2^2

8 can be rewritten as 2^3

Hence, the given expression becomes

2^5/2^3=2^2

After subtracting the exponents on left hand side of the equation we get:

2^2=2^2

we can do it by simplifying 8 to 2^3 to make both powers base two, and subtracting the exponents.

Ok 1/4 hour is 15 minutes. So 6:54 -2:15
4:39 pm is your start time

Answer:

4:39 PM

Step-by-step explanation:

Working with time can be tricky sometimes

This is what you know

Start time + elapsed time = end time

Using this equation we know that

start time + 2.25 hours= 6:54 pm

This is something that we can solve by subtracting 2.25 hours from each side, however, we first need to convert the .25 hours into minutes. We can do this by multiplying .25*60 which gets us 15. This means that 2 hours and 15 minutes has elapsed

So it's really just a question of 2 hours and 15 minutes - 6:54

This is pretty simple and you should get
