Best ResponseYou've already chosen the best response.1im not really sure, i suck at fractions :/

Best ResponseYou've already chosen the best response.1dont worry about fractions. it's easy. you have two things: 6c^3*d and 8b^2*d^2 open up, the numbers: 6,8 variables: c^3, d variables: b^2 d^2 agree?

Best ResponseYou've already chosen the best response.1So the LCD will be, 6*8 = 48 for variables, c^3 and b^2. now what about d and d^2 we always take the bigger term, so we will take d^2. Therefore our LCD will be, 48*c^3*b^2*d^2

Best ResponseYou've already chosen the best response.1for the most part, yeah

Best ResponseYou've already chosen the best response.1What we have to do is, we have to make the denominators same as LCD. so we had 6c^3d.. and we have to make it as 48c^3b^2d^2 we have to multiply 6c^3d with something to make it as 48c^3b^2d^2 so we multiplied by 8b^2d.

Best ResponseYou've already chosen the best response.1oh okay and for the numerator??

Best ResponseYou've already chosen the best response.1When we multiply that for denominator, we multiply the same thing with numerator.

Best ResponseYou've already chosen the best response.1how do i multiply that out though? :/

Best ResponseYou've already chosen the best response.1\[\Large \frac{48c^3b^2d^2}{6c^3d} \to8b^2d.\]

Best ResponseYou've already chosen the best response.1woah..thats the numerator?

Best ResponseYou've already chosen the best response.1that's what u have to multiply with numerator.

Best ResponseYou've already chosen the best response.1i must be driving you crazy, lol, but i dont get how to multiply it and simplify afterwards.. :/

Best ResponseYou've already chosen the best response.1i got the denominator, now i need to get the numerator and then simplify. i know what to multiply but i dont know how :/ i get some super long answer with a bunch of variables

saifoo.khan

Best ResponseYou've already chosen the best response.1whatever you multiply with denominator.. you have to multiply the same thing with the numerator.

Best ResponseYou've already chosen the best response.1So now, u(8b^2d) = 8b^2du

Best ResponseYou've already chosen the best response.1you forgot to multiply the right denominator and then the numerator.

Best ResponseYou've already chosen the best response.1you did it with left one right? now do it with right one as well.

Best ResponseYou've already chosen the best response.1so it would be 6c^3*d(3c^3*w^3)?

saifoo.khan
 2 years ago
Best ResponseYou've already chosen the best response.1No. since the denominators are different. we will do something like:dw:1339903883124:dw

Best ResponseYou've already chosen the best response.1ohh okay and once i get that, the top would be 8b^2du18c^6w^3?

saifoo.khan

Best ResponseYou've already chosen the best response.1Yes sir. that answer over \[\Large \frac{8b^2du18c^6w^3}{48c^3 b^2 d^2}\]
