It does, he just didn’t show that a/√a simplifies to √a. There are a couple ways to think about it, but the simplest is if you just wanna get rid of the square root in the denominator, you can multiply the entire left side by (√a/√a) which gives you a√a / √a√a. This then turns into a√a/a. From there you get to just √a

Fucking hell, thank you. I thought I was going quite mad - I'd just taken a detour in solving it instead.
Cheers friend!

We're the anti-meme community where the joke is that there isn't one, and by explaining that, we've ruined the whole thing, but we all find the collective misery hilarious.
The music of comedy is more important than the joke itself.

Alright, education time needed!
I'm a fair few years out from my entry level uni maths module, so:
In between the second and third step of the solution, why is 1a / 2√a = 6
not evaluating as
a/√a = 12 ?
