simplify 8x^{-9}

Solution

simplify

8 x^{- 9}

\frac{8}{x ^{9}}

Solution steps

8 x^{- 9}

Apply exponent rule:

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

x^{- 9} = \frac{1}{x ^{9}}

= 8 \cdot \frac{1}{x ^{9}}

Apply the fraction rule:

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

= \frac{8 \cdot 1}{x ^{9}}

Multiply the numbers:

8 \cdot 1 = 8

= \frac{8}{x ^{9}}

(w^{2})^{4}

\frac{y ^{8}}{( y ^{3} )}

\frac{cos ( a )}{( 1 - sin ( a ) ) - ( \frac{1}{c o s ( a )} )}

(3 x + 2 y - 4) \cdot (x - y + 2)

4 x^{4} y^{8} + (x^{2} y^{4})^{4} + 4
