(3y/x^4)^-3

1/(1+square root of a)

what would be the best solution:
(1)/(x-2) +8= (x)/(x-2)

• math -

( 3 y / x ^ 4 )^ - 3 =

1 / [ ( 3 y / x ^ 4 )^ 3 ] =

--------------------

Remark:

3 ^ 3 = 27

( x ^ 4 ) ^ 3 = x ^ ( 4 * 3 ) = x ^ 12

-----------------------

1 / ( 27 y ^ 3 / x ^ 12 ] =

x ^ 12 / 27 y ^ 3
