simplify (4.5)^2e^{-4.5}

Solution

simplify

(4.5)^{2} e^{- 4.5}

Solution

0.22495 \dots

Solution steps

(4.5)^{2} e^{- 4.5}

Apply exponent rule:

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

= 4. 5^{2} \cdot \frac{1}{e ^{4.5}}

Multiply fractions:

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

= \frac{1 \cdot 4. 5 ^{2}}{e ^{4.5}}

Multiply:

1 \cdot 4. 5^{2} = 4. 5^{2}

= \frac{4. 5 ^{2}}{e ^{4.5}}

4. 5^{2} = 20.25

= \frac{20.25}{e ^{4.5}}

e^{4.5} = 90.01713 \dots

= \frac{20.25}{90.01713 \dots}

Divide the numbers:

\frac{20.25}{90.01713 \dots} = 0.22495 \dots

= 0.22495 \dots
