Solve for d V = square root of e/d

$V = \sqrt{\frac{e}{d}}$

Step 1

Rewrite the equation as $\sqrt{\frac{e}{d}} = V$ .

$\sqrt{\frac{e}{d}} = V$

Step 2

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

${\sqrt{\frac{e}{d}}}^{2} = V^{2}$

Step 3

Simplify each side of the equation.

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

${({(\frac{e}{d})}^{\frac{1}{2}})}^{2} = V^{2}$

Simplify the left side.

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

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

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

${(\frac{e}{d})}^{\frac{1}{2} \cdot 2} = V^{2}$

Cancel the common factor of $2$ .

Cancel the common factor.

${(\frac{e}{d})}^{\frac{1}{2} \cdot 2} = V^{2}$

Rewrite the expression.

${(\frac{e}{d})}^{1} = V^{2}$

Simplify.

$\frac{e}{d} = V^{2}$

Step 4

Solve for $d$ .

Find the LCD of the terms in the equation.

Finding the LCD of a list of values is the same as finding the LCM of the denominators of those values.

$d, 1$

The LCM of one and any expression is the expression.

$d$

Multiply each term in $\frac{e}{d} = V^{2}$ by $d$ to eliminate the fractions.

Multiply each term in $\frac{e}{d} = V^{2}$ by $d$ .

$\frac{e}{d} d = V^{2} d$

Simplify the left side.

Cancel the common factor of $d$ .

Cancel the common factor.

$\frac{e}{d} d = V^{2} d$

Rewrite the expression.

$e = V^{2} d$

Solve the equation.

Rewrite the equation as $V^{2} d = e$ .

$V^{2} d = e$

Divide each term in $V^{2} d = e$ by $V^{2}$ and simplify.

Divide each term in $V^{2} d = e$ by $V^{2}$ .

$\frac{V^{2} d}{V^{2}} = \frac{e}{V^{2}}$

Simplify the left side.

Cancel the common factor of $V^{2}$ .

Cancel the common factor.

$\frac{V^{2} d}{V^{2}} = \frac{e}{V^{2}}$

Divide $d$ by $1$ .

$d = \frac{e}{V^{2}}$

Solve for d V = square root of e/d
