simplify 7e^{-1.86}

Solution

simplify

7 e^{- 1.86}

1.08970 \dots

Solution steps

7 e^{- 1.86}

Apply exponent rule:

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

= 7 \cdot \frac{1}{e ^{1.86}}

Multiply fractions:

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

= \frac{1 \cdot 7}{e ^{1.86}}

Multiply the numbers:

1 \cdot 7 = 7

= \frac{7}{e ^{1.86}}

e^{1.86} = 6.42373 \dots

= \frac{7}{6.42373 \dots}

Divide the numbers:

\frac{7}{6.42373 \dots} = 1.08970 \dots

= 1.08970 \dots

(\frac{2}{5})^{- 2^{^{'}}}
