simplify 9x^{-4}

Solution

simplify

9 x^{- 4}

\frac{9}{x ^{4}}

Solution steps

9 x^{- 4}

Apply exponent rule:

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

x^{- 4} = \frac{1}{x ^{4}}

= 9 \cdot \frac{1}{x ^{4}}

Apply the fraction rule:

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

= \frac{9 \cdot 1}{x ^{4}}

Multiply the numbers:

9 \cdot 1 = 9

= \frac{9}{x ^{4}}

28 \cdot 7

1 + (x - \frac{1}{4 x})^{2}

7 \frac{4}{5}
