Question

How do u know if variables go in numerator or denominator? how do u know where it goes?

Answer 1

A variable goes as a denominator if it's index is negative.

For example:

`x^(-1)y=(y)/(x)`

The index of x is -1, this makes it a denominator.

The given expression:

`x^4y^(-14)z^4=(x^4z^4)/(z^(14))`
