simplify 4e^{-1.2(-2)}

Solution

simplify

4 e^{- 1.2 (- 2)}

Solution

44.09270 \dots

Solution steps

4 e^{- 1.2 (- 2)}

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{(- 2) \cdot 1.2}}

Remove parentheses:

(- a) = - a

= 4 \cdot \frac{1}{e ^{- 1.2 \cdot 2}}

\frac{1}{e ^{- 1.2 \cdot 2}} = e^{2.4}

= 4 e^{2.4}

e^{2.4} = 11.02317 \dots

= 4 \cdot 11.02317 \dots

Multiply the numbers:

4 \cdot 11.02317 \dots = 44.09270 \dots

= 44.09270 \dots
