simplify 9e^{-4^2}

Solution

simplify

9 e^{- 4^{2}}

\frac{9}{e ^{16}}

Solution steps

9 e^{- 4^{2}}

Apply exponent rule:

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

= 9 \cdot \frac{1}{e ^{4^{2}}}

Multiply fractions:

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

= \frac{1 \cdot 9}{e ^{4^{2}}}

Multiply the numbers:

1 \cdot 9 = 9

= \frac{9}{e ^{4^{2}}}

4^{2} = 16

= \frac{9}{e ^{16}}

(x y)^{2}

\frac{( 1 - cos ( x ) ) ^{2}}{sin ^{2} ( x )}

\frac{3 ^{n}}{2 ^{n}}
