Explain how I solve this by rationalizing the denominator?

OpenStudy (mrnebula):

\[\frac{ 4\sqrt6 }{ \sqrt{30} }\]

OpenStudy (mrnebula):

@welshfella

OpenStudy (igigighjkl):

I can try.

OpenStudy (mrnebula):

Okay I been trying too but i fell like im doing it wrong

OpenStudy (mrnebula):

No, explain

OpenStudy (igigighjkl):

are those division symbols?

OpenStudy (mrnebula):

What ones?

OpenStudy (igigighjkl):

4 and 6

OpenStudy (mrnebula):

No thats a square root symbol. Do you know Algebra?

OpenStudy (igigighjkl):

No i'm in 6th grade sorry.

@pooja195

OpenStudy (mrnebula):

Ok, thanks anyways :)

OpenStudy (welshfella):

sqrt6 / sqrt 30 = 1 / sqrt5

OpenStudy (mrnebula):

Wait what?

OpenStudy (welshfella):

\[\sqrt{6}\div \sqrt{30} = \sqrt{5}\]

OpenStudy (mrnebula):

Oh ok

OpenStudy (welshfella):

sorry that's 1 / square root of 5

OpenStudy (mrnebula):

Is that all I do, or is there more?

OpenStudy (welshfella):

well theres the 4 in the numerator

OpenStudy (mrnebula):

Ya so do I just 4sqrt{5}?

OpenStudy (welshfella):

= 4/sqrt 5 now rationalize the denominator Multiply numerator and denominator by sqrt 5

OpenStudy (welshfella):

THis will give you \[4 \sqrt{5} / 5\]

OpenStudy (mrnebula):

Ok

OpenStudy (mrnebula):

Thanks!
