That equation can be written as,
= (3^2)^m/3^-2 = (3^2)^4
= 3^2m/3^-2 = 3^8
= 3^2m+2 = 3^8
= 2m + 2 = 8
m = 3
Hope this helps!

wrong answer
Okk.. Sorry.. I think the answer is 3. last step I did a mistake. 2m + 2 = 8, 2m = 6, m = 3

Hlo friend..
3^2m ÷ 3^-2= ( 3²)⁴
3^2m-(-2) = 3^8
3^2m+2 = 3^8
When the bases are same, then powers will equate.
2m + 2 = 8
2m = 8-2
2m = 6
m = 6/2
m = 3
HOPE IT HELPS YOU.. PLS MARK ME AS BRAINLIEST..
