Solve the Rational Equation for x -6+ square root of x+10=2

$- 6 + \sqrt{x + 10} = 2$

Move all terms not containing $\sqrt{x + 10}$ to the right side of the equation.

Add $6$ to both sides of the equation.

$\sqrt{x + 10} = 2 + 6$

Add $2$ and $6$ .

$\sqrt{x + 10} = 8$

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

${\sqrt{x + 10}}^{2} = 8^{2}$

Simplify each side of the equation.

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x + 10}$ as ${(x + 10)}^{\frac{1}{2}}$ .

${({(x + 10)}^{\frac{1}{2}})}^{2} = 8^{2}$

Simplify the left side.

Simplify ${({(x + 10)}^{\frac{1}{2}})}^{2}$ .

Multiply the exponents in ${({(x + 10)}^{\frac{1}{2}})}^{2}$ .

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

${(x + 10)}^{\frac{1}{2} \cdot 2} = 8^{2}$

Cancel the common factor of $2$ .

Cancel the common factor.

${(x + 10)}^{\frac{1}{2} \cdot 2} = 8^{2}$

Rewrite the expression.

${(x + 10)}^{1} = 8^{2}$

Simplify.

$x + 10 = 8^{2}$

Simplify the right side.

Raise $8$ to the power of $2$ .

$x + 10 = 64$

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

Subtract $10$ from both sides of the equation.

$x = 64 - 10$

Subtract $10$ from $64$ .

$x = 54$
