simplify (-2h^5)(4h^{-3})

simplify

(- 2 h^{5}) (4 h^{- 3})

- 8 h^{2}

Solution steps

(- 2 h^{5}) (4 h^{- 3})

Apply rule:

(- a) = - a

(- 2 h^{5}) = - 2 h^{5}

= - 2 h^{5} \cdot 4 h^{- 3}

Multiply the numbers:

- 2 \cdot 4 = - 8

= - 8 h^{5} h^{- 3}

Apply exponent rule:

a^{b} \cdot a^{c} = a^{b + c}

h^{5} h^{- 3} = h^{5 - 3}

= - 8 h^{5 - 3}

Subtract the numbers:

5 - 3 = 2

= - 8 h^{2}

\frac{( \frac{\frac{a}{b}}{\frac{c}{d}} )}{\frac{e}{f}}

(- 243 x^{- 15})^{\frac{1}{5}}

5^{- 1}

\frac{a ^{1}}{2}

9 x + 1 = 10 x - 5
