simplify (8.1310^{-6})(4pi(1.22)^2)

simplify

(8.13 \cdot 1 0^{- 6}) \cdot (4 \cdot π \cdot (1.22)^{2})

0.00015 \dots

Solution steps

(8.13 \cdot 1 0^{- 6}) (4 π (1.22)^{2})

Apply exponent rule:

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

= 4 \cdot 1.2 2^{2} \cdot 8.13 π \frac{1}{1 0 ^{6}}

Multiply fractions:

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

= 8.13 \cdot \frac{1 \cdot 4 \cdot 1.2 2 ^{2} π}{1 0 ^{6}}

\frac{1 \cdot 4 π 1.2 2 ^{2}}{1 0 ^{6}} = 0.00001 \dots

= 0.00001 \dots \cdot 8.13

Multiply the numbers:

8.13 \cdot 0.00001 \dots = 0.00015 \dots

= 0.00015 \dots

0.0195 \cdot 143.6 3^{0.77} \cdot 0.027 8^{- 0.385}

\frac{a}{b} cos^{2} (a) e^{- \frac{a ^{2}}{b ^{2}}}

4.55 \cdot 1 0^{- 1}

200 e^{- 41}

e^{t} \cdot 1^{- 1}
