Hi, I hope I've got the right place to post. I've a test tomorrow and on the mock this question came up and I am confused about it.
The question is 'Make y the subject of: 6t2 = 5ay2 '
My working so far is divide both sides by 5a (6t2/5a=y2). Then do the square root of both sides (not sure if I do square root of just 6t2 or the whole side (6t2/5a)? Giving me 2.44t/5a = y.
My teacher has done y2=6t2/5a > y=square root of (6t2/5a) = t square root of (6/5a) I am most confused about this t square root. So his answer is y=t square root of 6/5a
Appreciate any help here, cheers
