Question

State whether true or false:

If $x^3=11$, then $x=\sqrt[3]{311}$

• A. True
• B. False

Answer 1

The correct option is A True

TRUE:

Odd exponents preserve the sign of the original expression. Therefore, if $x^3$ is positive, then $x$ must itself be positive. IF $x^3=11$, then $x$ must be $\sqrt[3]{311}$
