$\sqrt{s \sqrt{s^{4}}}$

Step 1

Rewrite $s^{4}$ as ${(s^{2})}^{2}$ .

$\sqrt{s \sqrt{{(s^{2})}^{2}}}$

Step 2

Pull terms out from under the radical, assuming positive real numbers.

$\sqrt{s \cdot s^{2}}$

Step 3

Multiply $s$ by $s^{2}$ by adding the exponents.

Step 3.1.1

Raise $s$ to the power of $1$ .

$\sqrt{s^{1} s^{2}}$

Step 3.1.2

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\sqrt{s^{1 + 2}}$

Step 3.2

Add $1$ and $2$ .

$\sqrt{s^{3}}$

Step 4

Factor out $s^{2}$ .

$\sqrt{s^{2} s}$

Step 5

Pull terms out from under the radical.

$s \sqrt{s}$
