Question

Multiplicative inverse of 7^-2

Answer 1

7²

Explanation:

the product of a number and its multiplicative inverse is equal to 1 , that is

a ×
`(1)/(a)` = 1

given

`7^(-2)` , then multiplicative inverse is
`(1)/(7^(-2) )` = 7² and

`7^(-2)` × 7² =
`7^(0)` = 1

Answer 2

`7^2`

Explanation:

• multiplicative inverse of
  `\:\:7^(-2) =7^2`
