Congratulations!

OpenStudy (zzr0ck3r):

that was a flatland joke

OpenStudy (zzr0ck3r):

sqrt(70) = sqrt(35*4) = sqrt(35)*sqrt(4) = ?

OpenStudy (anonymous):

@zzr0ck3r lmao? & I'm confused, lol.

OpenStudy (zzr0ck3r):

sqrt(a*b) = sqrt(a)*sqrt(b)

OpenStudy (anonymous):

@zzr0ck3r so the answer would be...

OpenStudy (anonymous):

@callie2240

OpenStudy (zzr0ck3r):

we are not here to give answers:) what is 35*4?

OpenStudy (zzr0ck3r):

you can type it into google if you want the answer...

OpenStudy (anonymous):

@zzr0ck3r 140??

OpenStudy (zzr0ck3r):

yes so sqrt(140) = sqrt(35*4) right?

OpenStudy (anonymous):

@zzr0ck3r yes

OpenStudy (zzr0ck3r):

so since sqrt(a*b) = sqrt(a)*sqrt(b) what is sqrt(35*4)

OpenStudy (zzr0ck3r):

cmon we are close, don't wait for callie...

OpenStudy (anonymous):

@zzr0ck3r actually, my computer lags ahaha.. & umm... ach i hate math!

OpenStudy (zzr0ck3r):

...

OpenStudy (anonymous):

split 140 into two numbers sqrt(10*14) now keep simplifying i know u can do it i agree with @zzr0ck3r u can do it :d but im here if u need help

OpenStudy (zzr0ck3r):

nono not 10*14

OpenStudy (zzr0ck3r):

look at his answers

OpenStudy (anonymous):

@zzr0ck3r is it D?

OpenStudy (zzr0ck3r):

yes

OpenStudy (anonymous):

i know it not 10*14 i said keep simplifying lol like 10 is 5*2 and 14is 7*2

OpenStudy (zzr0ck3r):

sqrt(4)*sqrt(35) = 2sqrt(35)

OpenStudy (anonymous):

thanks!!

OpenStudy (anonymous):

sqrt(5*2*7*2) 2 would be on the outside. and it would be 5 *7 so 2sqrt(35)
