simplify the radical: I'll post it,one sec.
\[3\sqrt{18x^2}\] @jhonyy9
18 = ? how can you rewrite the 18 like a product of a square number and a number
i took the sqrt of 18 and made it into \[\sqrt{9} * \sqrt{2}\] then the sqrt of 9 is 3 that's how the teacher taught us. is that correct.
yes correct
so how will get simplified this all ?
so then she told us to find the sqrt of x^2 and i got x is that right?
yes
and the sqrt of 9 = ?
3
exactly ansd so inside radical will remain just what ?
is it 2? because the sqrt of 18 was \[\sqrt{9} * \sqrt{2}\] and sqrt 2 can't be simplified ?
yes correct so now please write me here how will be this 3sqrt18x^2 simplified ?
but wait, what about the 3 in front of the radical? so i multiply it with the 3 from the sqrt of 9?
yes - what is the problem with this 3 ? nothing
ok so we will have \[3*3x \sqrt{2}\] and will that be \[9x \sqrt{2}\]
perfect - congrats - hope you understand it now sure right
yes, thank you!!
yw - anytime - with my pleasure
