Question

Write three powers with whole-number bases that have values greater than 120 and less than 130. The three powers, in order from least to greatest, are , , and .

Answer 1

11²= 121

5³= 125

2⁷= 128

Explanation:

The whole numbers can be multiplied with themselves to get numbers between 120 and 130 .

For example

11*11= 121

This can be written in the exponent form as

11²= 121 which is between 120 and 130.

Also

5*5*5= 125 or

5³= 125 which is also between 120 and 130.

and

2*2*2*2*2*2*2= 128

2⁷= 128 which is between 120 and 130 as required.

We see that as the powers or exponent increases the whole number is decreased.
