Answer:
m=5
Step-by-step explanation:
5^m-3*3^2m-8=225. (^) this is the symbol of raise to the power
5^m*3^2m-8=25*9
5^m-3*3^2m-8=5^2*3^2
3^2m-8=3^2. we are taking 3^2m-8=3^2 so that it is easy to calculate
2m-8=2. by taking the powers of 3
2m=2+8
2m=10
m=10/2
m=5
5^m-3=5^5-3
=5^2=25
3^2m-8=3^2(5)-8
=3^2=9
25*9=225
DONE
