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

Step 1

Subtract $\sqrt{x}$ from both sides of the equation.

$x^{2} - \sqrt{x} = 0$

Step 2

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

$x^{2} - x^{\frac{1}{2}} = 0$

Step 3.1

Factor $x^{\frac{1}{2}}$ out of $x^{2}$ .

$x^{\frac{1}{2}} x^{\frac{3}{2}} - x^{\frac{1}{2}} = 0$

Step 3.2

Factor $x^{\frac{1}{2}}$ out of $- x^{\frac{1}{2}}$ .

$x^{\frac{1}{2}} x^{\frac{3}{2}} + x^{\frac{1}{2}} \cdot - 1 = 0$

Step 3.3

Factor $x^{\frac{1}{2}}$ out of $x^{\frac{1}{2}} x^{\frac{3}{2}} + x^{\frac{1}{2}} \cdot - 1$ .

$x^{\frac{1}{2}} (x^{\frac{3}{2}} - 1) = 0$

Step 4

Rewrite $x^{\frac{3}{2}}$ as ${(x^{\frac{1}{2}})}^{3}$ .

$x^{\frac{1}{2}} ({(x^{\frac{1}{2}})}^{3} - 1) = 0$

Step 5

Rewrite $1$ as $1^{3}$ .

$x^{\frac{1}{2}} ({(x^{\frac{1}{2}})}^{3} - 1^{3}) = 0$

Step 6

Since both terms are perfect cubes, factor using the difference of cubes formula, $a^{3} - b^{3} = (a - b) (a^{2} + a b + b^{2})$ where $a = x^{\frac{1}{2}}$ and $b = 1$ .

$x^{\frac{1}{2}} ((x^{\frac{1}{2}} - 1) ({(x^{\frac{1}{2}})}^{2} + x^{\frac{1}{2}} \cdot 1 + 1^{2})) = 0$
