Short Answer

Expert verified

The simplification of $36^{\frac{1}{2}}$ is $6$

The simplification of $8^{\frac{1}{3}}$ is $2$

The simplification of $16^{\frac{1}{4}}$ is $2$

Step by step solution

Part (a) Step 1. Given

An expression $36^{\frac{1}{2}}$

To simplify the expression.

Part (a) Step 2. Rewrite as perfect nth power

Rewrite as a square root.

$36^{\frac{1}{2}} = \sqrt{36}$

Recognize $36$ as a perfect square.

$= \sqrt{6^{2}}$

$= 6$

Part (b) Step 1. Given

An expression $8^{\frac{1}{3}}$

To simplify the expression.

Part (b) Step 2. Rewrite as perfect nth power

Rewrite as a cube root.

$8^{\frac{1}{3}} = \sqrt[3]{8}$

Recognize $8$ as a perfect cube.

$= \sqrt[3]{2^{3}}$

$= 2$

Part (c) Step 1. Given

An expression $16^{\frac{1}{4}}$

To simplify the expression.

Part (c) Step 2. Rewrite as perfect nth power

Rewrite as a fourth root.

$16^{\frac{1}{4}} = \sqrt[4]{16}$

Recognize $16$ as a perfect fourth power.

$= \sqrt[4]{2^{4}}$

$= 2$
