Write the following in simplified radical form.

[tex]\[ \sqrt[4]{162 w^{13}} \][/tex]

Assume that the variable represents a positive real number.



Answer :

Sure, let's simplify the given expression step by step. We need to simplify the radical expression:

[tex]\[ \sqrt[4]{162 w^{13}} \][/tex]

First, let's break down the expression inside the radical. Notice that:

[tex]\[ 162 = 2 \times 81 = 2 \times 3^4 \][/tex]

Therefore, we can rewrite the expression under the fourth root as:

[tex]\[ \sqrt[4]{2 \times 3^4 \times w^{13}} \][/tex]

We know that the fourth root of a product can be written as the product of the fourth roots. So, we can break this down and take the fourth root of each component individually:

[tex]\[ \sqrt[4]{2 \times 3^4 \times w^{13}} = \sqrt[4]{2} \times \sqrt[4]{3^4} \times \sqrt[4]{w^{13}} \][/tex]

Next, we simplify each part. The fourth root of [tex]\(3^4\)[/tex] is straightforward:

[tex]\[ \sqrt[4]{3^4} = 3 \][/tex]

For [tex]\(w^{13}\)[/tex], we can write:

[tex]\[ \sqrt[4]{w^{13}} = w^{13/4} \][/tex]

Putting it all together, we have:

[tex]\[ \sqrt[4]{2} \times 3 \times w^{13/4} \][/tex]

Therefore, the radical expression [tex]\(\sqrt[4]{162w^{13}}\)[/tex] simplifies to:

[tex]\[ 3 \sqrt[4]{2} w^{13/4} \][/tex]

Thus, the simplified radical form is:

[tex]\[ 3 \cdot 2^{1/4} \cdot (w^{13})^{1/4} \][/tex]

Which can also be written as:

[tex]\[ 3 \cdot 2^{1/4} \cdot w^{13/4} \][/tex]

And that's our final simplified form.
