Solve by Factoring cube root of 5x-3=-2

$\sqrt[3]{5 x - 3} = - 2$

Step 1

Add $2$ to both sides of the equation.

$\sqrt[3]{5 x - 3} + 2 = 0$

Step 2

Subtract $2$ from both sides of the equation.

$\sqrt[3]{5 x - 3} = - 2$

Step 3

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

${\sqrt[3]{5 x - 3}}^{3} = {(- 2)}^{3}$

Step 4

Simplify each side of the equation.

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt[3]{5 x - 3}$ as ${(5 x - 3)}^{\frac{1}{3}}$ .

${({(5 x - 3)}^{\frac{1}{3}})}^{3} = {(- 2)}^{3}$

Simplify the left side.

Simplify ${({(5 x - 3)}^{\frac{1}{3}})}^{3}$ .

Multiply the exponents in ${({(5 x - 3)}^{\frac{1}{3}})}^{3}$ .

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

${(5 x - 3)}^{\frac{1}{3} \cdot 3} = {(- 2)}^{3}$

Cancel the common factor of $3$ .

Cancel the common factor.

${(5 x - 3)}^{\frac{1}{3} \cdot 3} = {(- 2)}^{3}$

Rewrite the expression.

${(5 x - 3)}^{1} = {(- 2)}^{3}$

Simplify.

$5 x - 3 = {(- 2)}^{3}$

Simplify the right side.

Raise $- 2$ to the power of $3$ .

$5 x - 3 = - 8$

Step 5

Solve for $x$ .

Move all terms not containing $x$ to the right side of the equation.

Add $3$ to both sides of the equation.

$5 x = - 8 + 3$

Add $- 8$ and $3$ .

$5 x = - 5$

Divide each term in $5 x = - 5$ by $5$ and simplify.

Divide each term in $5 x = - 5$ by $5$ .

$\frac{5 x}{5} = \frac{- 5}{5}$

Simplify the left side.

Cancel the common factor of $5$ .

Cancel the common factor.

$\frac{5 x}{5} = \frac{- 5}{5}$

Divide $x$ by $1$ .

$x = \frac{- 5}{5}$

Simplify the right side.

Divide $- 5$ by $5$ .

$x = - 1$
