Evaluate 2/3 square root of x=6

$\frac{2}{3} \sqrt{x} = 6$

Step 1

Multiply both sides of the equation by $\frac{3}{2}$ .

$\frac{3}{2} (\frac{2}{3} \cdot \sqrt{x}) = \frac{3}{2} \cdot 6$

Step 2

Simplify both sides of the equation.

Simplify the left side.

Simplify $\frac{3}{2} (\frac{2}{3} \cdot \sqrt{x})$ .

Combine $\frac{2}{3}$ and $\sqrt{x}$ .

$\frac{3}{2} \cdot \frac{2 \sqrt{x}}{3} = \frac{3}{2} \cdot 6$

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3}{2} \cdot \frac{2 \sqrt{x}}{3} = \frac{3}{2} \cdot 6$

Rewrite the expression.

$\frac{1}{2} (2 \sqrt{x}) = \frac{3}{2} \cdot 6$

Cancel the common factor of $2$ .

Factor $2$ out of $2 \sqrt{x}$ .

$\frac{1}{2} (2 (\sqrt{x})) = \frac{3}{2} \cdot 6$

Cancel the common factor.

$\frac{1}{2} (2 \sqrt{x}) = \frac{3}{2} \cdot 6$

Rewrite the expression.

$\sqrt{x} = \frac{3}{2} \cdot 6$

Simplify the right side.

Simplify $\frac{3}{2} \cdot 6$ .

Cancel the common factor of $2$ .

Factor $2$ out of $6$ .

$\sqrt{x} = \frac{3}{2} \cdot (2 (3))$

Cancel the common factor.

$\sqrt{x} = \frac{3}{2} \cdot (2 \cdot 3)$

Rewrite the expression.

$\sqrt{x} = 3 \cdot 3$

Multiply $3$ by $3$ .

$\sqrt{x} = 9$

Step 3

To remove the radical on the left side of the equation, square both sides of the equation.

${\sqrt{x}}^{2} = 9^{2}$

Step 4

Simplify each side of the equation.

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

${(x^{\frac{1}{2}})}^{2} = 9^{2}$

Simplify the left side.

Simplify ${(x^{\frac{1}{2}})}^{2}$ .

Multiply the exponents in ${(x^{\frac{1}{2}})}^{2}$ .
