w^12/w^18 =?

1. w^30
2. w^-30
3. w^6
4. w^-6

Answer 1

@Kainui

Answer 2

Try thinking about a simple example like:

x^3/x^2. If you write it out, you get (x*x*x)/(x*x) which simplifies to x. So you can see it's just 3-2=1 for the exponents.

Answer 3

@Kainui So, it would be w^-6

Answer 4

\[x^a * x^b = x^{a + b}\]\[\frac{ x^a }{ x^b } = x^{a-b}\]

Answer 5

Yeah you got it.

Answer 6

Thanks!
