Question

what's the value of x when x 20 squared

Answer 1

Since we do not know the value of x, we cannot solve x to the power 20. Therefore, x to the power 20 will remain x to the power 20

Answer 2

Step-by-step explanation:

x-root x = 20

Squaring on both sides

x² - x - 20 = 0

x² + 4x - 5x - 20 = 0

x(x + 4) - 5(x + 4) = 0

(x + 4) (x - 5) = 0

X = - 4,5
