Given that - 1 / 3 ^ 2A ^ m-1b ^ 2 = 4 ^ 3A ^ 2B ^ n-1 is a similar term, try to judge whether x = (M + n) / 2 is the solution of the equation - 2x-6 = 0

Given that - 1 / 3 ^ 2A ^ m-1b ^ 2 = 4 ^ 3A ^ 2B ^ n-1 is a similar term, try to judge whether x = (M + n) / 2 is the solution of the equation - 2x-6 = 0

-If 1 / 3 ^ 2A ^ m-1b ^ 2 and 4 ^ 3A ^ 2B ^ n-1 are of the same kind, then a and B are equal
n-1=2;m-1=2
So m = 3, n = 3, (M + n) / 2 = 3
-2*3-6=0
So 3 is the solution of the equation, so x = (M + n) / 2 is the solution of the equation - 2x - 6 = 0
