I WILL FAN AND MEDAL IF YOU CAN HELP ME WITH SOME SIMLE ALGEBRA!!!!!! :)
Simplify the rational expression by rationalizing the denominator.

\[\frac{ 4 \sqrt{150} }{ \sqrt{189x} }\]
OpenStudy (cggurumanjunath):
150=2*75=2*3*25=2*3*5*5
OpenStudy (cggurumanjunath):
4*sqrt (150) =4*5*sqrt (2*3)=20*sqrt 6
OpenStudy (anonymous):
Wait which part do you want me to solve?
OpenStudy (cggurumanjunath):
189=3*63=3*21*3=3*3*3*7

20*sqrt6 =?
OpenStudy (cggurumanjunath):
sqrt (189)=sqrt(3*3*3*7)=3*sqrt (21)
OpenStudy (anonymous):
@CGGURUMANJUNATH no offense but I think your confusing @Darealest123 lol
OpenStudy (cggurumanjunath):
numerator = 20*sqrt (6)
OpenStudy (anonymous):
Also answer choices are:
a 20*sqrt150/sqrt189x
b 4/sqrt189x
c 4*sqrt39x/189x
d 16/189x

OpenStudy (cggurumanjunath):
denominator = sqrt (189*x) = 3*sqrt (21*x)
OpenStudy (cggurumanjunath):

Darealest what grade is this?
OpenStudy (anonymous):
grade? you mean course?
OpenStudy (cggurumanjunath):
numerator =n
denominator =d

no like what grade math is this lol I know its algebra but like what level? 10th, 9th, 11th
OpenStudy (cggurumanjunath):
20*sqrt (6) / 3 *sqrt (21x)
OpenStudy (anonymous):
so it would be 20*sqrt6/3*sqrt21*x
OpenStudy (anonymous):
but thats not an answer choice so do i simplify the numbers?
OpenStudy (cggurumanjunath):
yes !
