Question

WILL MEDAL AND FAN YOU PLESE I NEED TO GET THIS DONE BY MIDNIGHT
3sqrt(12)xsqrt(6)

Answer 1

it's multiplying it not a variable for the x

Answer 2

I'm using the rule \(\Large \sqrt{xy} = \sqrt{x}*\sqrt{y}\)


\[\Large 3*\sqrt{12}*\sqrt{6}\]
\[\Large 3*\sqrt{12*6}\]
\[\Large 3*\sqrt{72}\]
\[\Large 3*\sqrt{36*2}\]
\[\Large 3*\sqrt{36}*\sqrt{2}\]
\[\Large 3*6*\sqrt{2}\]
\[\Large 18*\sqrt{2}\]

-------------------------------------------------------
So,\[\Large 3*\sqrt{12}*\sqrt{6}=18*\sqrt{2}\]

Answer 3

THANK YOU THANK YOU THANK YOU!! can you help me with like 5 more please?

Answer 4

I'll help with 2 more

Answer 5

ok let me pick which 2 i need the most help on.

Answer 6

alright

Answer 7

ok 4/sqrt5

Answer 8

\[\frac{ 4 }{ \sqrt{5} }\]

Answer 9

Multiply top and bottom by \(\large \sqrt{5}\) to rationalize the denominator

\[\large \frac{4}{\sqrt{5}}\]
\[\large \frac{4*\sqrt{5}}{\sqrt{5}*\sqrt{5}}\]
\[\large \frac{4\sqrt{5}}{\sqrt{5*5}}\]
\[\large \frac{4\sqrt{5}}{\sqrt{25}}\]
\[\large \frac{4\sqrt{5}}{5}\]
-------------------------------------------------------
Therefore, \[\large \frac{4}{\sqrt{5}}=\frac{4\sqrt{5}}{5}\]

Answer 10

Notice how I used the rule \(\Large \sqrt{xy} = \sqrt{x}*\sqrt{y}\) again

Answer 11

ok i know you said you'd only help with one more after this but can you help two? i got the other two now, but there's still two more im really, really stuck on :(

Answer 12

just one more

Answer 15

alright

Answer 16

THANK YOU! :) ok this is the one i just need you to check, then we can do the other

Answer 17

Answer 18

\[12\sqrt{6}\]
