simplify 8x^{-4}

Solution

simplify

8 x^{- 4}

\frac{8}{x ^{4}}

Solution steps

8 x^{- 4}

Apply exponent rule:

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

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

= 8 \cdot \frac{1}{x ^{4}}

Apply the fraction rule:

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

= \frac{8 \cdot 1}{x ^{4}}

Multiply the numbers:

8 \cdot 1 = 8

= \frac{8}{x ^{4}}

- 4 x^{2} - 8 x + (- x^{2}) - 6 x + 8

1 \div \frac{5}{2}

32.6 + (- 56.24)

\frac{27 m - 36 n}{36 m - 48 n}

x^{2} \cdot (- 4)
