anonymous · Answer

3x^3y^3 squareroot 2xy is what i got

anonymous · Answer

so 3x^3y^4 sqrt 2x so D

anonymous · Answer

how'd u get 3x^3y^3 squareroot 2xy

loser66 · Answer

still need help?

anonymous · Answer

sorry for the late reply i was eating dinner, yeah I really have no clue on how to do this

loser66 · Answer

work with me is hard, ready?

anonymous · Answer

i'm ready

loser66 · Answer

under the square root, you have 3 terms, number, x and y. We solve one by one
now number 18 = 9*2  ok? and 9 = $3^2$ so, 18 = $3^2 *2$ got this?

loser66 · Answer

now, you tell me 2$\div$2 =? remainder =?

anonymous · Answer

1?

loser66 · Answer

anonymous · Answer

oh 0 there is no remainder

loser66 · Answer

loser66 · Answer

give me the answer of 5$\div$2=               remainder

anonymous · Answer

a^2.5
5/2 - 2.5 ?

loser66 · Answer

be patient, not that,, just answer me, I spend time to tutor you step by step , if you jump, you cannot get the method.

anonymous · Answer

ok
but 5/2 does equal 2.5 right?

loser66 · Answer

yes, but no, because I ask you for quotient and remainder

anonymous · Answer

i'm confused 
what do you mean by quotient?
I thought the remainder is what you were left with which is 2.5 so what is a quotient (sorry for being so stupid :c )
