Step 1.1.1

Apply the rule

x^{\frac{m}{n}} = \sqrt[n]{x^{m}}

$x^{\frac{m}{n}} = \sqrt[n]{x^{m}}$ to rewrite the exponentiation as a radical.

\sqrt[3]{{(5 x - 6)}^{1}}

$\sqrt[3]{{(5 x - 6)}^{1}}$

Step 1.1.2

Anything raised to

1

$1$ is the base itself.

\sqrt[3]{5 x - 6}

$\sqrt[3]{5 x - 6}$

\sqrt[3]{5 x - 6}

$\sqrt[3]{5 x - 6}$

Step 1.2

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Step 2

Since the domain is all real numbers,

${(5 x - 6)}^{\frac{1}{3}}$ is continuous over all real numbers.
