Question

Cube root of $8$ are $+2$ and $-2$.

• A. True
• B. False

Answer 1

The correct option is B False

Cube root of $8$$=$$\sqrt[3]{8}$

Exponent form of $8$$=$$2\times 2\times 2=2^3$

Therefore, $\sqrt[3]{8}$$=\sqrt[3]{2^3}={\left(2^3\right)}^{\frac{1}{3}}=2$

Hence, the cube root of $8$ is $2$.
