Solve for x square root of x-3 = square root of x-3

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

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

${\sqrt{x - 3}}^{2} = {\sqrt{x - 3}}^{2}$

Simplify each side of the equation.

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x - 3}$ as ${(x - 3)}^{\frac{1}{2}}$ .

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

Simplify the left side.

Simplify ${({(x - 3)}^{\frac{1}{2}})}^{2}$ .

Multiply the exponents in ${({(x - 3)}^{\frac{1}{2}})}^{2}$ .

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

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

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

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

Simplify.

$x - 3 = {\sqrt{x - 3}}^{2}$

Simplify the right side.

Rewrite ${\sqrt{x - 3}}^{2}$ as $x - 3$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{x - 3}$ as ${(x - 3)}^{\frac{1}{2}}$ .

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

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

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

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

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

Cancel the common factor of $2$ .

Cancel the common factor.

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

Rewrite the expression.

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

Simplify.

$x - 3 = x - 3$

Solve for $x$ .

Move all terms containing $x$ to the left side of the equation.

Subtract $x$ from both sides of the equation.

$x - 3 - x = - 3$

Combine the opposite terms in $x - 3 - x$ .

Subtract $x$ from $x$ .

$0 - 3 = - 3$

Subtract $3$ from $0$ .

$- 3 = - 3$

Since $- 3 = - 3$ , the equation will always be true for any value of $x$ .
