Answer: x=-9

Step-by-step explanation:

I was wrong originally looked again and here we are me questioning my existence as human being and the other person is right of x= -9. I used desmos took m advice and just plugged in the $\sqrt[5]{32}x^{5}$ and made it equal to $\sqrt[5]{(3x+9)^5}$ by writing them as seperate equation on desmos and they collide on the point (-9, -18) which proves the other person work

Answer:
x = -9

Explanation:

(3x + 9)^5 = 32x^5

(3 (x + 3))^5 = 32x^5

3^5 (x + 3)^5 = 32x^5

243(x + 3)^5 = 32x^5

243(x + 3)^5 - 32x^5 = 0

x = -9
