3^m = 81
3^m = 3^4
m = 4

3^(m - 2) = 3^(4 - 2)
               = 3²
               = 9

3^(m + 2) = 3^(4 + 2)
                = 3^6
                = 729

Hope this helps you.

trobo: this answer is correct so thanks

3ⁿ =81
81 = 3⁴
⇒ 3ⁿ = 3⁴
n=4

3ⁿ⁻² = 3⁴⁻² =3² = 9
3ⁿ⁺² = 3⁴⁺² = 3⁶ =729








Hope it helps... :)
