Answer:  x = 0, x = 9

Step-by-step explanation:

x = 3√x            Restriction: x ≥ 0

(x)² = (3√x)²      square both sides

x² = 9x              simplified

x² - 9x = 0        subtracted 9x from both sides

x(x - 9) = 0       factored quadratic equation

x = 0  and    x - 9 = 0         applied zero product property

x = 0  and   x = 9              solved for x

Both solutions satisfy the restriction!
