simplify 4*e^{-2}

Solution

simplify

4 \cdot e^{- 2}

\frac{4}{e ^{2}}

Decimal Notation

0.54134 \dots

Solution steps

4 e^{- 2}

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{2}}

Multiply fractions:

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

= \frac{1 \cdot 4}{e ^{2}}

Multiply the numbers:

1 \cdot 4 = 4

= \frac{4}{e ^{2}}

e^{- 1. 2^{2}}

32.744 e^{- 0.252}

\frac{\frac{x ^{2}}{y}}{\frac{x}{y}}

\frac{1}{3} (7^{2} + 1)^{- \frac{2}{3}} \cdot 4

(e^{- 7})^{\frac{6}{7}}
