simplify 4pi10^{-7}8.81450.21

simplify

4 π \cdot 1 0^{- 7} \cdot 8.8 \cdot 145 \cdot 0.21

0.00033 \dots

Solution steps

4 π 1 0^{- 7} \cdot 8.8 \cdot 145 \cdot 0.21

Apply exponent rule:

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

= 4 \cdot 145 \cdot 0.21 \cdot 8.8 π \frac{1}{1 0 ^{7}}

Multiply fractions:

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

= 0.21 \cdot 8.8 \cdot \frac{1 \cdot 4 \cdot 145 π}{1 0 ^{7}}

\frac{1 \cdot 4 π 145}{1 0 ^{7}} = \frac{29 π}{500000}

= 0.21 \cdot 8.8 \cdot \frac{29 π}{500000}

Multiply the numbers:

8.8 \cdot 0.21 = 1.848

= 1.848 \cdot \frac{29 π}{500000}

Multiply fractions:

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

= \frac{29 π 1.848}{500000}

Multiply the numbers:

29 \cdot 1.848 = 53.592

= \frac{53.592 π}{500000}

Multiply the numbers:

53.592 \cdot 3.14159 \dots = 168.36423 \dots

= \frac{168.36423 \dots}{500000}

Divide the numbers:

\frac{168.36423 \dots}{500000} = 0.00033 \dots

= 0.00033 \dots
