$\sqrt{\frac{3}{2}}$ as

\frac{\sqrt{3}}{\sqrt{2}}

$\frac{\sqrt{3}}{\sqrt{2}}$ .

\frac{\sqrt{3}}{\sqrt{2}}

$\frac{\sqrt{3}}{\sqrt{2}}$

Step 2

Multiply

\frac{\sqrt{3}}{\sqrt{2}}

$\frac{\sqrt{3}}{\sqrt{2}}$ by

\frac{\sqrt{2}}{\sqrt{2}}

$\frac{\sqrt{2}}{\sqrt{2}}$ .

\frac{\sqrt{3}}{\sqrt{2}} \cdot \frac{\sqrt{2}}{\sqrt{2}}

Step 3.1

Multiply

\frac{\sqrt{3}}{\sqrt{2}}

$\frac{\sqrt{3}}{\sqrt{2}}$ by

\frac{\sqrt{2}}{\sqrt{2}}

$\frac{\sqrt{2}}{\sqrt{2}}$ .

\frac{\sqrt{3} \sqrt{2}}{\sqrt{2} \sqrt{2}}

$\frac{\sqrt{3} \sqrt{2}}{\sqrt{2} \sqrt{2}}$

Step 3.2

Raise

\sqrt{2}

$\sqrt{2}$ to the power of

1

$1$ .

\frac{\sqrt{3} \sqrt{2}}{{\sqrt{2}}^{1} \sqrt{2}}

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

Step 3.3

Raise

\sqrt{2}

$\sqrt{2}$ to the power of

1

$1$ .

\frac{\sqrt{3} \sqrt{2}}{{\sqrt{2}}^{1} {\sqrt{2}}^{1}}

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

Step 3.4

Use the power rule

a^{m} a^{n} = a^{m + n}

$a^{m} a^{n} = a^{m + n}$ to combine exponents.

\frac{\sqrt{3} \sqrt{2}}{{\sqrt{2}}^{1 + 1}}

$\frac{\sqrt{3} \sqrt{2}}{{\sqrt{2}}^{1 + 1}}$

Step 3.5

Add

1

$1$ and

1

$1$ .

Step 3.6.1

Use

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

$\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite

\sqrt{2}

$\sqrt{2}$ as

2^{\frac{1}{2}}

$2^{\frac{1}{2}}$ .

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

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

Step 3.6.2

Apply the power rule and multiply exponents,

{(a^{m})}^{n} = a^{m n}

${(a^{m})}^{n} = a^{m n}$ .

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

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

Step 3.6.3

Combine

\frac{1}{2}

$\frac{1}{2}$ and

2

$2$ .

\frac{\sqrt{3} \sqrt{2}}{2^{\frac{2}{2}}}

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