simplify-4pi10^{-7}8

Solution

simplify

- 4 π \cdot 1 0^{- 7} \cdot 8

Solution

- \frac{π}{312500}

+1

Solution steps

- 4 π 1 0^{- 7} \cdot 8

Apply exponent rule:

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

= - 4 \cdot 8 π \frac{1}{1 0 ^{7}}

Multiply fractions:

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

= - \frac{1 \cdot 4 π 8}{1 0 ^{7}}

Multiply the numbers:

1 \cdot 4 \cdot 8 = 32

= - \frac{32 π}{1 0 ^{7}}

Cancel

\frac{32 π}{1 0 ^{7}} : \frac{π}{5 ^{7} \cdot 2 ^{2}}

= - \frac{π}{5 ^{7} \cdot 2 ^{2}}

5^{7} \cdot 2^{2} = 312500

= - \frac{π}{312500}
