It's your friend's birthday, and you want to use binary numbers for the candles on their cake. Your plan is to use
green candles to mean "on" and gray candles to mean "off".
What's the least number of candles you need in order to represent the age 18?

Answer:

5 candles

Explanation:

2⁴ = 16, that's not enough

2⁵ = 32, that is plenty

The value would be 10010, or green-gray-gray-green-gray.

At least 5 candles are needed.

Binary is a base-2 number system that uses two states 0 and 1 to represent a number. We can also call it to be a true state and a false state. A binary number is built the same way as we build the normal decimal number.

According to the given concept

The binary representation can be [tex]2^{4}[/tex] which results in 16.

But we need for age 18 years.

So,

[tex]2^{5}[/tex] = 32 which is greater than 18.

Hence, 5 candles are needed.
