simplify 4e^{-(0)}

Solution

simplify

4 e^{- (0)}

4

Solution steps

4 e^{- (0)}

Apply exponent rule:

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

= 4 \cdot \frac{1}{e ^{0}}

Apply rule

a^{0} = 1, a \neq = 0

e^{0} = 1

= 4 \cdot \frac{1}{1}

Multiply fractions:

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

= \frac{1 \cdot 4}{1}

Cancel the common factor:

1

= 4

2.45 \cdot 1 0^{0} \cdot \frac{1 0 ^{- 3}}{1 0 ^{0}}

\frac{1}{3} π r^{2} \cdot 2 r

1.225 e^{- (\frac{0.04}{288.15}) 2000}
