simplify 4pi10^{-7}*2.8

Solution

simplify

4 \cdot π \cdot 1 0^{- 7} \cdot 2.8

Solution

3.51858 E - 6

Solution steps

4 π 1 0^{- 7} \cdot 2.8

Apply exponent rule:

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

= 4 \cdot 2.8 π \frac{1}{1 0 ^{7}}

Multiply fractions:

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

= 2.8 \cdot \frac{1 \cdot 4 π}{1 0 ^{7}}

\frac{1 \cdot 4 π}{1 0 ^{7}} = \frac{π}{2500000}

= 2.8 \cdot \frac{π}{2500000}

Multiply fractions:

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

= \frac{π 2.8}{2500000}

Multiply the numbers:

3.14159 \dots \cdot 2.8 = 8.79645 \dots

= \frac{8.79645 \dots}{2500000}

Divide the numbers:

\frac{8.79645 \dots}{2500000} = 3.51858 E - 6

= 3.51858 E - 6
