Question

How would you write numbers in powers of 2?

Ex. Write as a power of 2.

a)32
b)2

What is the answer, and how did you get it?

Answer 1

You use to the powers of (often called indices or orders) when you wish to shorten something like 5 x 5 x 5 x 5 to 5^4 (^ meaning to the power of)

2^1 =2
2^5 = 32

We can work this out because
2 = 2
2x2=4
2x2x2=8
2x2x2x2=16
2x2x2x2x2=32

In the future use the homework help section under education and referances - there are more people there solving questions/problems.

Answer 2

32 = 2 x 2 x 2 x 2 x 2 = 2^5
2 = 2^1

Answer 3

a. 2x2x2x2x2 =32 = 2^5
there are 5 twos multiplied together thisis 2^5 by definition.

b 2^1 by the same reasoning as above
