Question

For what value of a does (1/9)^a+1 = 81^a+1 x 27^2-a?

Answer 1

A should equal to -3 or -4 depending on whether what the equation is. 

For example, if it's (1/9)^(a+1)=81^(a+1) x 27^(2-a), then the answer is -4.

But if it's the other way stated above, then it should be -3.

Hope this helps.

Answer 2

The answer for a should equal to -3 in the equation given

Solution:
(1/9)^(a+1)=81^(a+1) x 27^(2-a), then the answer would be a=-3.
