From the question
W are given
[tex]a=6[/tex]
We are to find the value of
[tex]a^{-2}[/tex]
To do this, we will simply substitute the value of a into the expression
Since a = 6. then
[tex]a^{-2}=6^{-2}[/tex]
By applying exponential property
We have
[tex]6^{-2}=\frac{1}{6^2}[/tex]
Thefore the corrcet answer is
[tex]\frac{1}{6^2}[/tex]
