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

    Hello, clockingly!

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

    Are there any suggestions of what is expected?

    If not, both e^{-2x} + 0 and 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
