Step-by-step explanation:
Simplify the following expression then state the property used:
9^-2
Property:
Given,
9^-2
For any real numbers a and b a, b ≠ 0, and for any two positive integers, n and n
a^-m
=> 1/a^m [By doing reciprocal]
So,
9^-2
=> 1/9^2
=> 1/(3^2)^2
=> 1/(3^4)
=> 1/(3*3*3*3)
=> 1/81. Ans.
Hope this helps.
