Question

12/square root of 15 Simplify, but keep in radical form.

Answer 1

\[12\div \sqrt{15}\]

Answer 2

12/3.872=3.099

Answer 3

I have to keep it in radical form, so is it already simplified?

Answer 4

okay... \[12= 2*\sqrt{3}.....\frac{ 2*\sqrt{3} }{ \sqrt{3}\sqrt{5} }\]

Answer 5

can you do it now...?

Answer 6

alright, I see it. Thanks :)

Answer 7

:)

Answer 8

@ghazi how did you get: \(12=2*\sqrt{3}\)

Answer 9

this would be true only for: \(\sqrt{12}=\sqrt{4*3}=2\sqrt{3}\)

Answer 10

yea...i see it...it seems i have made a mistake...exactly @anaseer you're right

Answer 11

@cocoa020 what you need to do here is multiply the numerator and the denominator by \(\sqrt{15}\) and then simplify

Answer 12

i didn't see it's not under square root

Answer 13

so:\[\frac{12}{\sqrt{15}}=\frac{12}{\sqrt{15}}\times\frac{\sqrt{15}}{\sqrt{15}}=\frac{12\sqrt{15}}{15}\]

Answer 14

the idea is to ensure you don't have any radicals in the denominator

Answer 15

does that make sense @cocoa020 ?
