Please help me solve this!!!!

Question

4*(3-x)^4/3 - 5 = 59
(4/3 is an exponent)
I got to this far... (3-x)^4/3 = 16
But how do I get rid of the exponent? Please help me my final is tomorrow and I still don't know :(

Answer 1

(3-x)^4/3 = 16 , great so far
raise both sides to the 3/4
[(3-x)^4/3]^(3/4) = 16^(3/4)
3-x = 8
x = -5
