Simplify the expression. (128x5/8x)1/4 enter your answer in the box

2x

Step-by-step explanation:

(128x^5/8x)^1/4

Simplify inside the parenthesis first

128/8 = 16

x^5/x

x^4

(128x^5/8x)^1/4

(16x^4) ^ 1/4

(ab)^c = a^c  8b^c

16 ^1/4   * x^4 ^ 1/4

a^b^c = a^ (b*c)

16 ^ 1/4 * x^(4*1/4)

2 * x^1  

2*x
