Let 3 (a power) = 4 (B power) = 36, then 2 / a (fraction) + 1 / b (fraction)= Originally the teacher said, forget to copy, now how can't think of
A power of 3 = B power of 4 = 36
Then a = log3 (36)
b=log4(36)
Then 2 / a = 2log36 (3) = log36 (9)
1/b=log36(4)
Then 2 / A + 1 / b = log36 (9) + log36 (4) = log36 (36) = 1
