simplify 0.045210e^{-2}

simplify

0.045 \cdot 2 \cdot 10 e^{- 2}

0.12180 \dots

Solution steps

0.045 \cdot 2 \cdot 10 e^{- 2}

Apply exponent rule:

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

= 2 \cdot 10 \cdot 0.045 \cdot \frac{1}{e ^{2}}

Multiply fractions:

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

= 0.045 \cdot \frac{1 \cdot 2 \cdot 10}{e ^{2}}

Multiply the numbers:

1 \cdot 2 \cdot 10 = 20

= 0.045 \cdot \frac{20}{e ^{2}}

Multiply fractions:

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

= \frac{20 \cdot 0.045}{e ^{2}}

Multiply the numbers:

20 \cdot 0.045 = 0.9

= \frac{0.9}{e ^{2}}

Convert element to a decimal form

e^{2} = 7.38905 \dots

= \frac{0.9}{7.38905 \dots}

Divide the numbers:

\frac{0.9}{7.38905 \dots} = 0.12180 \dots

= 0.12180 \dots
