To solve for x in the equation x^3 = 21, you can take the cube root of both sides:
x = ∛21
To simplify the cube root of 21, you can factor it into prime factors:
21 = 3 * 7
So, x = ∛(3 7)x = ∛3 ∛7x = ∛(3) ∛(7)x = 3^(1/3) 7^(1/3)
Therefore, the solution to the equation x^3 = 21 is x = 3^(1/3) * 7^(1/3) or approximately x = 2.758.
