Simplify - square root of 3*(- square root of 3)

$- \sqrt{3} \cdot (- \sqrt{3})$

Step 1

Multiply $- \sqrt{3} (- \sqrt{3})$ .

Multiply $- 1$ by $- 1$ .

$1 \sqrt{3} \sqrt{3}$

Multiply $\sqrt{3}$ by $1$ .

$\sqrt{3} \sqrt{3}$

Raise $\sqrt{3}$ to the power of $1$ .

${\sqrt{3}}^{1} \sqrt{3}$

Raise $\sqrt{3}$ to the power of $1$ .

${\sqrt{3}}^{1} {\sqrt{3}}^{1}$

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

${\sqrt{3}}^{1 + 1}$

Add $1$ and $1$ .

${\sqrt{3}}^{2}$

Step 2

Rewrite ${\sqrt{3}}^{2}$ as $3$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{3}$ as $3^{\frac{1}{2}}$ .

${(3^{\frac{1}{2}})}^{2}$

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

$3^{\frac{1}{2} \cdot 2}$

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

$3^{\frac{2}{2}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$3^{\frac{2}{2}}$

Rewrite the expression.

$3^{1}$

Evaluate the exponent.

$3$
