Exponential function negative: ( 81 4 ) 1 / 4 ( 1 4 ) 3 / 4
Multiply on both sides equals 81 1 / 4 4 1 / 4 1 3 / 4 4 3 / 4
This should be 3 4 1 / 4 1 3 / 4 4 3 / 4 which I get to -3/ 4 1 / 2
Is that correct? I should get the answer 6.

An alternative way (bring everything under a single exponent):
( 81 4 ) 1 4 ( 1 4 ) 3 4 = ( 81 4 ) 1 4 [ ( 1 4 ) 3 ] 1 4 = ( 81 4 ) 1 4 ( 4 3 ) 1 4 = ( 81 4 64 ) 1 4 = ( 81 16 ) 1 4 = 3 2 = 6
