simplify 4e^{-1.5}

Solution

simplify

4 e^{- 1.5}

0.89252 \dots

Solution steps

4 e^{- 1.5}

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{1.5}}

Multiply fractions:

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

= \frac{1 \cdot 4}{e ^{1.5}}

Multiply the numbers:

1 \cdot 4 = 4

= \frac{4}{e ^{1.5}}

e^{1.5} = 4.48168 \dots

= \frac{4}{4.48168 \dots}

Divide the numbers:

\frac{4}{4.48168 \dots} = 0.89252 \dots

= 0.89252 \dots

\frac{5}{6} (0.5 - 1)^{- 2}

182 \cdot 1 0^{- 6} \cdot 0.05 \cdot 28
