How do you simplify 9x^(1/5)-2x^(1/5)?

Jun 22, 2018

$7 {x}^{\frac{1}{5}}$

or can be written as:

$7 \sqrt[5]{x}$

Explanation:

$9 {x}^{\frac{1}{5}} - 2 {x}^{\frac{1}{5}}$

Since the base is the same we can subtract the coefficients:

$9 {x}^{\frac{1}{5}} - 2 {x}^{\frac{1}{5}} = 7 {x}^{\frac{1}{5}}$
