Question

2 to 3 X x to 3 = [2 + x] to 3

Answer 1

Answer:

x = 2.

Step-by-step explanation:

I am taking this to mean

2^3 * x^3 = (2 + x)^3

8x^3 = (2 + x)(4 + 4x + x^2)

8x^3 = 8 + 8x + 2x^2 + 4x + 4x^2 + x^3

7x^3 - 6x^2 - 12x - 8 = 0

7(2)^3 - 6(2)^2 - 12(2) - 8

= 56 - 24 - 24 - 8 = 0

x = 2.

This is the only real root.
