$\tan (\arcsin (\frac{4}{7}))$

Step 1

Multiply $\frac{4}{\sqrt{33}}$ by $\frac{\sqrt{33}}{\sqrt{33}}$ .

$\frac{4 \sqrt{33}}{\sqrt{33} \sqrt{33}}$

Step 2

Raise $\sqrt{33}$ to the power of $1$ .

$\frac{4 \sqrt{33}}{{\sqrt{33}}^{1} \sqrt{33}}$

Step 3

Raise $\sqrt{33}$ to the power of $1$ .

$\frac{4 \sqrt{33}}{{\sqrt{33}}^{1} {\sqrt{33}}^{1}}$

Step 4

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

$\frac{4 \sqrt{33}}{{\sqrt{33}}^{1 + 1}}$

Step 5

Add $1$ and $1$ .

$\frac{4 \sqrt{33}}{{\sqrt{33}}^{2}}$

Step 6

Rewrite ${\sqrt{33}}^{2}$ as $33$ .

Step 6.1

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{33}$ as $33^{\frac{1}{2}}$ .

$\frac{4 \sqrt{33}}{{(33^{\frac{1}{2}})}^{2}}$

Step 6.2

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

$\frac{4 \sqrt{33}}{33^{\frac{1}{2} \cdot 2}}$

Step 6.3

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

$\frac{4 \sqrt{33}}{33^{\frac{2}{2}}}$

Step 6.4

Cancel the common factor of $2$ .
