Question

FIND THE VALUE OF m FOR WHICH 9^m / 3^-2 = 9^4 .

Answer 1

Click on the name of any element to see its chemical properties, environmental data or effects on health.

The only cause we were able to answer this question is because (-2)^2m, where m is an integer, is raised to an even power.

Hence

(-2)^(2m) = 4^m  

and  

2^(9-m) = 4^((9-m)/2)  

Therefore,  

m = (9-m)/2  

2m = 9 - m  

m = 3
