simplify 6.910^{-6}4pi(1.3^2)

simplify

6.9 \cdot 1 0^{- 6} \cdot 4 \cdot π \cdot (1. 3^{2})

0.00014 \dots

Solution steps

6.9 \cdot 1 0^{- 6} \cdot 4 π (1. 3^{2})

Apply exponent rule:

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

= 4 \cdot 1. 3^{2} \cdot 6.9 π \frac{1}{1 0 ^{6}}

Multiply fractions:

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

= 6.9 \cdot \frac{1 \cdot 4 \cdot 1. 3 ^{2} π}{1 0 ^{6}}

\frac{1 \cdot 4 π 1. 3 ^{2}}{1 0 ^{6}} = 0.00002 \dots

= 0.00002 \dots \cdot 6.9

Multiply the numbers:

6.9 \cdot 0.00002 \dots = 0.00014 \dots

= 0.00014 \dots

0.5 e^{- 1}

100 e^{- 0.000462}
