Now. What do you think we divide by on both sideS?
 one year ago

vf321 Group TitleBest ResponseYou've already chosen the best response.2
yes. You get: \[u/v = (w2)^2\] Now you need to perform a certain operation to both sides to get rid of the ^2...

square root
 one year ago

vf321 Group TitleBest ResponseYou've already chosen the best response.2
Yes. You get: \[\sqrt{u/v}=\sqrt{(w2)^2}\]

Not quite. what's sqrt((5)^2)?
 one year ago

vf321 Group TitleBest ResponseYou've already chosen the best response.2
yes. And now that you've seen that, what do you think sqrt(x^2) is? it's not just x, since then the answer to sqrt((5)^2) would be 5...

storyw4 Group TitleBest ResponseYou've already chosen the best response.0
is the answer w=2v +u√(v)
 one year ago

vf321 Group TitleBest ResponseYou've already chosen the best response.2
Well what I got was \[\pm \sqrt{u/v}2\]
