I assume the given expression is


\sqrt x \sqrt[4]{x}

We can write each root as a rational power of x, then add the exponents:


\sqrt x \sqrt[4]{x} = x^(\frac12) x^(\frac14) = x^(\frac12 + \frac14) = x^(\frac34)

Then putting it back into radical form, we have


\sqrt x \sqrt[4]{x} = \sqrt[4]{x^3}
