Question

Acellus Change the negative exponent to a positive exponent. 11-8 = 1 [?]0

Answer 1

A negative exponent means that factor is on the wrong side of the fraction.

For example, $5^{-11}$ can be written as $\dfrac{5^{-11}}{1}$ and to get rid of that negative exponent, the $5^{-11}$ gets moved to the bottom and the exponent becomes positive.

     $5^{-11} = \dfrac{1}{5^{11}}$

And if the exponent is negative in the bottom, then you move that factor to the top:

    $\dfrac{1}{y^{-7}} = \dfrac{y^7}{1}$ and we just write that as $y^7$, since the "over 1" isn't needed.

The formatting of your question leaves me guessing a bit, but I think your original expression was $11^{-8}$.  Based on what we just talked about above, how would you rewrite that with a positive exponent?
