Answer 2

`5^(-3)`

Explanation:

Given the indicial expression

`(5^(-2))(5^(-1))`

First let us convert them to fraction;

5^-2 = 1/5^2

5^-2 = 1/25

Also;

5^-1 = 1/5^1

5^-2 = 1/5

Multiplying both fractions;

`(5^(-2))(5^(-1))` = 1/25 * 1/5

`(5^(-2))(5^(-1))` = 1/125

`(5^(-2))(5^(-1))` = 1/5^3

1/5^3 =
`5^(-3)`

Hence the required answer is
`5^(-3)`
