Question

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

uhmm.. I messed up then.

anonymous · Answer

$$(72st ^{3})/13$$

anonymous · Answer

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.

anonymous · Answer

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

anonymous · Answer

yes.

anonymous · Answer

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.

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

it's str8. :)

anonymous · Answer

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

anonymous · Answer

oh okay thank you for helping me.

anonymous · Answer

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

anonymous · Answer

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