Answer:
[tex]\frac{7^1^2}{9^2}[/tex]
Step-by-step explanation:
So like for #3 [tex](\frac{7^6}{9} )^2[/tex]
When you have an exponent raised to another exponent you would just multiply those two together.
So for the 7 it is raised to the 6 then again to the 2 so you would write this like
7 ^(6×2) which would result in [tex]7^1^2[/tex]
Now for the bottom, since you don't see an exponent it means it is raised to the power of 1, so 1×2 = 2 so the 9 would be raised to the 2 power.
The full simplification of this would be [tex]\frac{7^1^2}{9^2}[/tex]
