simplify 2x^{-2/7}

Solution

simplify

2 x^{- \frac{2}{7}}

\frac{2}{x ^{\frac{2}{7}}}

Solution steps

2 x^{- \frac{2}{7}}

Apply exponent rule:

a^{- b} = \frac{1}{a ^{b}}

x^{- \frac{2}{7}} = \frac{1}{x ^{\frac{2}{7}}}

= 2 \cdot \frac{1}{x ^{\frac{2}{7}}}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{2 \cdot 1}{x ^{\frac{2}{7}}}

Multiply the numbers:

2 \cdot 1 = 2

= \frac{2}{x ^{\frac{2}{7}}}

(x + 4) (x^{2} - 5 x + 9)

\frac{24 x ^{3}}{6 x}

144 a^{2} b^{4}

y^{3} + y^{2}

(2 + 3) \cdot (2 - 3)
