Simplify 2 square root of x*2 square root of x

$2 \sqrt{x} \cdot 2 \sqrt{x}$

Multiply $2 \sqrt{x} (2 \sqrt{x})$ .

Multiply $2$ by $2$ .

$4 \sqrt{x} \sqrt{x}$

Raise $\sqrt{x}$ to the power of $1$ .

$4 ({\sqrt{x}}^{1} \sqrt{x})$

Raise $\sqrt{x}$ to the power of $1$ .

$4 ({\sqrt{x}}^{1} {\sqrt{x}}^{1})$

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

$4 {\sqrt{x}}^{1 + 1}$

Add $1$ and $1$ .

$4 {\sqrt{x}}^{2}$

Rewrite ${\sqrt{x}}^{2}$ as $x$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x}$ as $x^{\frac{1}{2}}$ .

$4 {(x^{\frac{1}{2}})}^{2}$

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$4 x^{\frac{1}{2} \cdot 2}$

Combine $\frac{1}{2}$ and $2$ .
