Find the cube root of 8. Then, rewrite rational exponents as radicals and simplify.

1 answer

To find the cube root of 8, we can express this as:

\[ \sqrt[3]{8} \]

The cube root of 8 is 2, since \(2 \times 2 \times 2 = 8\). So, we have:

\[ \sqrt[3]{8} = 2 \]

Next, we can rewrite rational exponents as radicals. The expression for the cube root can be written as:

\[ 8^{\frac{1}{3}} \]

Now, to rewrite this using radicals, we have:

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

Since we already know that \(\sqrt[3]{8} = 2\), we have the simplified result:

\[ 2 \]

Therefore, the cube root of 8, expressed with rational exponents as radicals and simplified, is:

\[ \sqrt[3]{8} = 2 \]
