Question

The cube root of a number is 2. Write an equation, using x, that represents this situation.

Answer 1

x - 8 = 0

Explanation:

Since, the cube root of a number is 2.

Let the number be x.

Therefore,

`\sqrt[3]{x} = 2 \\ cubing \: both \: sides \\ {( \sqrt[3]{x})}^(3) = {(2)}^(3) \\ x = 8 \\ x - 8 = 0`
