simplify (7b^4)/(4b^{-1)}

Solution

simplify

\frac{7 b ^{4}}{4 b ^{- 1}}

Solution

\frac{7 b ^{5}}{4}

Solution steps

\frac{7 b ^{4}}{4 b ^{- 1}}

Apply exponent rule:

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

\frac{b ^{4}}{b ^{- 1}} = b^{4 - (- 1)}

= \frac{7 b ^{4 - (- 1)}}{4}

4 - (- 1) = 5

= \frac{7 b ^{5}}{4}
