Question

I am doing Coursera and there is an Interger Exponents question I am confused at>
Expression (4x^-3y^5z^-2)^-2/6y^-5z^5x^-8
equals Kz^r/x^sy^t where K= ??>
What do they mean by quote "where K =?

Answer 1

\[\frac{(4x^{-3}y^5z^{-2})^{-2}}{6y^{-5}z^5x^{-8}} = \frac{Kz^2}{x^sy^t}\]

After you simplify the thing on the left, you'll be left with something like what is on the right, except that K will be an expression, and they want you to find it.
