Examples

e^{x} = \frac{1}{e^{20}}

$e^{x} = \frac{1}{e^{20}}$

Step 1

Move

e^{20}

$e^{20}$ to the numerator using the negative exponent rule

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

$\frac{1}{b^{n}} = b^{- n}$ .

e^{x} = e^{- 20}

$e^{x} = e^{- 20}$

Step 2

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

x = - 20

$x = - 20$
