Transcript text: $(\sqrt[4]{16 x})^{3}$ use rational exponents to put this in different form
Solution
Solution Steps
To express \((\sqrt[4]{16x})^3\) using rational exponents, we first convert the fourth root into a rational exponent. The fourth root of a number is the same as raising that number to the power of \(1/4\). Therefore, \(\sqrt[4]{16x}\) can be written as \((16x)^{1/4}\). Raising this expression to the power of 3 involves multiplying the exponents.
Step 1: Express the Fourth Root Using Rational Exponents
The expression given is \((\sqrt[4]{16x})^3\). The fourth root of a number can be expressed using rational exponents as raising the number to the power of \(\frac{1}{4}\). Therefore, we can rewrite \(\sqrt[4]{16x}\) as:
\[
(16x)^{\frac{1}{4}}
\]
Step 2: Apply the Power of a Power Rule
The expression \((\sqrt[4]{16x})^3\) can now be rewritten using the expression from Step 1:
\[
((16x)^{\frac{1}{4}})^3
\]
According to the power of a power rule, \((a^m)^n = a^{m \cdot n}\). Applying this rule, we have:
