18st^4/52s^3t * 16s^3/9s^2t (multiplying radical expression) plz help.

OpenStudy (anonymous):

first simplify through division. you'll get...\[(9t ^{3}/26)*(16s/t)\]

OpenStudy (anonymous):

Then multiply across. Numerator times numerator. Denominator times denominator.

OpenStudy (anonymous):

I think I know the answer I got 8t^2/13s? but I'm not 100% sure.

OpenStudy (anonymous):

There shouldn't be any s's in the denominator since the higher powered s's are in the numerator.

OpenStudy (anonymous):

uhmm.. I messed up then.

OpenStudy (anonymous):

\[(72st ^{3})/13\]

OpenStudy (anonymous):

It's cool. Just go back to the beginning and try again. You've got some of the steps and the answer now, so you can check your work along the way.

OpenStudy (anonymous):

It was...\[(18st ^{4}/52s ^{3}t)*(16s ^{3}/9s ^{2}t)\] right?

OpenStudy (anonymous):

yes.

OpenStudy (anonymous):

Then yeah. Before doing any multiplication and getting ridiculously high numbers and powers, help yourself first by dividing coefficients and subtracting exponents where you can.

OpenStudy (anonymous):

I took an easier way I got 288 divide by 468 =8/13 I just can figure out the variables.

OpenStudy (anonymous):

Well, it is 8/13 my apologies. I completely forgot the 9 under the 16

OpenStudy (anonymous):

it's str8. :)

OpenStudy (anonymous):

I messed up. It helps to write math down correctly. You had the right answer waaaaaay up above somewhere beyond my wrong responses.

OpenStudy (anonymous):

oh okay thank you for helping me.

OpenStudy (anonymous):

Ha! I apologize for wasting your time! Take care.

OpenStudy (anonymous):

it's okay, at least you took the time to help. and now I know I have the write answer. and u2
