Simplify (x^(2/3)-x^(1/3))(x^(2/3)+x^(1/3))

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

Step 1

Expand $(x^{\frac{2}{3}} - x^{\frac{1}{3}}) (x^{\frac{2}{3}} + x^{\frac{1}{3}})$ using the FOIL Method.

Apply the distributive property.

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

Apply the distributive property.

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

Apply the distributive property.

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

Step 2

Simplify terms.

Combine the opposite terms in $x^{\frac{2}{3}} x^{\frac{2}{3}} + x^{\frac{2}{3}} x^{\frac{1}{3}} - x^{\frac{1}{3}} x^{\frac{2}{3}} - x^{\frac{1}{3}} x^{\frac{1}{3}}$ .

Reorder the factors in the terms $x^{\frac{2}{3}} x^{\frac{1}{3}}$ and $- x^{\frac{1}{3}} x^{\frac{2}{3}}$ .

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

Subtract $x^{\frac{2}{3}} x^{\frac{1}{3}}$ from $x^{\frac{2}{3}} x^{\frac{1}{3}}$ .

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

Add $x^{\frac{2}{3}} x^{\frac{2}{3}}$ and $0$ .

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

Simplify each term.

Multiply $x^{\frac{2}{3}}$ by $x^{\frac{2}{3}}$ by adding the exponents.

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

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

Combine the numerators over the common denominator.

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

Add $2$ and $2$ .

$x^{\frac{4}{3}} - x^{\frac{1}{3}} x^{\frac{1}{3}}$

Multiply $x^{\frac{1}{3}}$ by $x^{\frac{1}{3}}$ by adding the exponents.

Move $x^{\frac{1}{3}}$ .

$x^{\frac{4}{3}} - (x^{\frac{1}{3}} x^{\frac{1}{3}})$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$x^{\frac{4}{3}} - x^{\frac{1}{3} + \frac{1}{3}}$

Combine the numerators over the common denominator.

$x^{\frac{4}{3}} - x^{\frac{1 + 1}{3}}$

Add $1$ and $1$ .

$x^{\frac{4}{3}} - x^{\frac{2}{3}}$

Simplify (x^(2/3)-x^(1/3))(x^(2/3)+x^(1/3))
