Note that,
$\displaystyle e^{-x}=\frac{1}{e^x}$
Thus,
$\displaystyle e^{-x}$
Und,
$\displaystyle \frac{1}{e^x}$
Are equal.

Hello, clockingly!

i have to find two expressions that are mathematically equal to $\displaystyle e^{-2x}$

Are there any suggestions of what is expected?

If not, both $\displaystyle e^{-2x} + 0$ and $\displaystyle e^{-2x} \times 1$ certainly work.

e^-2x

There are many ways of writing it.

1/(e^2x)

(1/e^x)^2

(e^-x)^2

(e^-x)/(e^x)

Take your pick
