So what do u think of LCD?

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
im not really sure, i suck at fractions :/
 2 years ago

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
dont 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?

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
So 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

oh okay perfect, then what??

now, dw:1339902810873:dwDo you get this step?

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
for the most part, yeah
 2 years ago

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
What 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.

oh okay and for the numerator??
 2 years ago

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

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
how do i multiply that out though? :/
 2 years ago

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

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
woah..thats the numerator?
 2 years ago

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
Yes sir.
 2 years ago

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
that's what u have to multiply with numerator.

i must be driving you crazy, lol, but i dont get how to multiply it and simplify afterwards.. :/

i 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
 2 years ago

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

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
So now, u(8b^2d) = 8b^2du
 2 years ago

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
so, 8b^2du  3c^3w^3?
 2 years ago

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
you forgot to multiply the right denominator and then the numerator.
 2 years ago

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
you did it with left one right? now do it with right one as well.
 2 years ago

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
so it would be 6c^3*d(3c^3*w^3)?
 2 years ago

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

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
ohh okay and once i get that, the top would be 8b^2du18c^6w^3?
 2 years ago

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

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
okay and does that get simplified further??

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
Yes. you can take commons.

jay3390 Group TitleBest ResponseYou've already chosen the best response.1
like the b^2?

saifoo.khan Group TitleBest ResponseYou've already chosen the best response.1
b^2 is not in the second term.
