simplify 4r^{-7}s^{-1}*7r^{-2}s^5t^0

simplify

4 r^{- 7} s^{- 1} \cdot 7 r^{- 2} s^{5} t^{0}

\frac{28 s ^{4}}{r ^{9}}

Solution steps

4 r^{- 7} s^{- 1} \cdot 7 r^{- 2} s^{5} t^{0}

Multiply the numbers:

4 \cdot 7 = 28

= 28 r^{- 7} s^{- 1} r^{- 2} s^{5} t^{0}

Simplify

r^{- 7} r^{- 2} : \frac{1}{r ^{9}}

= 28 \cdot \frac{1}{r ^{9}} s^{- 1} s^{5} t^{0}

Simplify

s^{- 1} s^{5} : s^{4}

= 28 \cdot \frac{1}{r ^{9}} s^{4} t^{0}

Simplify

28 \cdot \frac{1}{r ^{9}} s^{4} t^{0} : \frac{28 s ^{4}}{r ^{9}}

= \frac{28 s ^{4}}{r ^{9}}
