simplify pi0.310^{-2}*2

simplify

π \cdot 0.3 \cdot 1 0^{- 2} \cdot 2

0.01884 \dots

Solution steps

π 0.3 \cdot 1 0^{- 2} \cdot 2

Apply exponent rule:

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

= 2 \cdot 0.3 π \frac{1}{1 0 ^{2}}

Multiply fractions:

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

= 0.3 \cdot \frac{1 \cdot 2 π}{1 0 ^{2}}

\frac{1 π 2}{1 0 ^{2}} = \frac{π}{50}

= 0.3 \cdot \frac{π}{50}

Multiply fractions:

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

= \frac{π 0.3}{50}

Multiply the numbers:

3.14159 \dots \cdot 0.3 = 0.94247 \dots

= \frac{0.94247 \dots}{50}

Divide the numbers:

\frac{0.94247 \dots}{50} = 0.01884 \dots

= 0.01884 \dots

e^{- \frac{t}{10}}
