Question

Why does the 3 get put over the u^2v? The prior example and even on this question to the side it said it should be 1 over c^n. I’m so confused. Thanks.

Answer 1

u^-2 is the same as 1/u^2

3•u^-2 = 3/u^2

Answer 2

So why would it be 3/u^2v instead of 1/3u^2v?

In the example right before this problem it was 5u^-1 and it rewrote it as 1/5u.
