lol even the comment box was being stupid!

OpenStudy (turingtest):

factor what is under the radical sign completely then take out anything you have two of for instance, what is the prime factorization of 98 ?

OpenStudy (anonymous):

\[4\sqrt{2*49}=4*\sqrt{2*7^{2}}=28\sqrt{2}\]

OpenStudy (anonymous):

hurry, befor turing erase this....:)

OpenStudy (turingtest):

please note that myko is using the method I prescribed, so hopefully you won't have to ask this same type of question again

OpenStudy (anonymous):

okay i understand how now but what if there was a number like this.......

OpenStudy (anonymous):

|dw:1334327297294:dw|

OpenStudy (anonymous):

is that just an exponent for the 2?

OpenStudy (turingtest):

I'm not erasing the above because it does show steps if @ParisWinter does not understand what myko did, they should ask for explanation. In any case, I hope not to see the exact same type of question again... oh wait, here we go again what is the prime factorization of 128 ?

OpenStudy (anonymous):

64 i understand that but i dont understand what to do with the 3

OpenStudy (turingtest):

64 is not the prime factorization of 128 do you know how to factor?

OpenStudy (anonymous):

, ill figure it out but what do i need to do with 3

OpenStudy (amistre64):

the 3 just tells you what you can take out; ^3

OpenStudy (amistre64):

\[\sqrt[n]{a^n}=a\]

OpenStudy (anonymous):

take out of 128?

OpenStudy (amistre64):

take out from under the radical; does 128 have any perfect ^3s in it?

OpenStudy (anonymous):

no

OpenStudy (turingtest):

I think it does you should factor it and see

OpenStudy (amistre64):

128 = 2 * 64 = 2*2*32 = 2*2*2*16 =2*2*2*2*8 =2*2*2*2*2*4 =2*2*2*2*2*2*2 =(2*2*2)*(2*2*2)*2

OpenStudy (anonymous):

okay i dont see a three anywhere in that.

OpenStudy (amistre64):

do you see any groups that contain 3 of the same numbers?

OpenStudy (amistre64):

\[a*a*a = a^3\]
