split 128 in such a way that you can get a complete square like in last problem 9 was square of 3 thats why 63=9*7

\[\sqrt{128x^{5}y^2}\] 128 can be divided as 2*64 or \[2*8^{2}\] and x^5 as \[(x^2)^2*x\]

So\[\sqrt{2*8^2*(x^2)^2*x*y^2}\]

you take complete square terms outside like 64 = 8^2 when you take it out of root you get 8
 one year ago

aajugdar Group TitleBest ResponseYou've already chosen the best response.1
when you take y^2 out of root you get y

aajugdar Group TitleBest ResponseYou've already chosen the best response.1
and when you take x^4 out of root you get x^2

we have a relation \[\sqrt{a*b*c} = \sqrt{a}*\sqrt{b}*\sqrt{c}\]

Im so confused/:
 one year ago

SandeepReddy Group TitleBest ResponseYou've already chosen the best response.1
\[\sqrt{2*8^2*(x^2)^2*x*y^2}\] = \[\sqrt{2}*\sqrt{8^2}*\sqrt{(x^2)^2}*\sqrt{x}*\sqrt{y^2}\]
 one year ago

SandeepReddy Group TitleBest ResponseYou've already chosen the best response.1
that gives u \[\sqrt{2}*8*x^2*\sqrt{x}*y\]
 one year ago

SandeepReddy Group TitleBest ResponseYou've already chosen the best response.1
\[8\sqrt{2}x^{3/2}y\]

hmm could hv been easier to teach face to face answer is \[8x^2y \sqrt{2xy}\]
