simplify (1-30.75)e^{-3*0.75}

simplify

(1 - 3 \cdot 0.75) \cdot e^{- 3 \cdot 0.75}

- 0.13174 \dots

Solution steps

(1 - 3 \cdot 0.75) e^{- 3 \cdot 0.75}

Apply exponent rule:

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

= \frac{1}{e ^{3 \cdot 0.75}} (1 - 3 \cdot 0.75)

Multiply the numbers:

3 \cdot 0.75 = 2.25

= \frac{1}{e ^{2.25}} (1 - 2.25)

Subtract the numbers:

1 - 2.25 = - 1.25

= (- 1.25) \frac{1}{e ^{2.25}}

Remove parentheses:

(- a) = - a

= - 1.25 \cdot \frac{1}{e ^{2.25}}

Multiply fractions:

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

= - \frac{1 \cdot 1.25}{e ^{2.25}}

Multiply the numbers:

1 \cdot 1.25 = 1.25

= - \frac{1.25}{e ^{2.25}}

Simplify

\frac{1.25}{e ^{2.25}} : 0.13174 \dots

= - 0.13174 \dots

\frac{x ^{4}}{y ^{4}}

2.05 \cdot 100 0^{- 0, 18}
