Question

Simplify r^2a / r^2a-3. 2a and 2a-3 are radicals. Can you explain, also? Thanks!

Answer 1

\[\frac {r^2\sqrt{2a}} {r^2\sqrt{a-3}}\]

Yes?

Answer 2

Where do the radicals come from? Confused.. I don't think I learned this.

Answer 3

Is that the correct equation?

Your post says r^2a but then says 2a is a radical which does not make sense.

Answer 4

\[r^{\sqrt{2a}}\]

Or this?

Answer 5

Oh, I'm sorry. I meant 2a and 2a-3 are exponents. Apologies.

Answer 6

\[\frac{r^{2a}}{ r^{2a-3}}\]

Answer 7

Is that right?

Answer 8

\[r ^{2a} / r ^{2a-3}\]

Answer 9

Yeah, that's right. (:

Answer 10

Apply rule for exponents a^p /a^q = a^(p-q).

Answer 11

So it's r^(2a - 2a-3)?

Answer 12

yes, except it's 2a - (2a-3) which is different...

Answer 13

Oh, yeah. Sorry. Thank you very much. (:

Answer 14

u r welcome, if u don't like the equation editor, just use brackets to make things clear.
