- Akshay_Budhkar

ok hello again pokemon

- pokemon23

hello?

- Akshay_Budhkar

no check your \[1/2 \times \sqrt 20\]

- Akshay_Budhkar

what is \[\sqrt 20 = \sqrt {4 \times 5}\]

- Akshay_Budhkar

now you know\[\sqrt 4 =2\]

- Akshay_Budhkar

so
\[\sqrt 20 = 2 \times \sqrt 5\]

- SamIam

hey akshay is helping u out. He is good

- Akshay_Budhkar

but you want \[1/2 \sqrt 20 = \sqrt 5\]

- Akshay_Budhkar

you fine till here man?

- Akshay_Budhkar

Hey samlam thanks hehe

- pokemon23

so lost?

- Akshay_Budhkar

ok what is that you don't get?

- Akshay_Budhkar

square root of 20 is square root of 4*5

- SamIam

|dw:1326249125280:dw|

- SamIam

|dw:1326249164510:dw| did u get that?

- Akshay_Budhkar

\[\sqrt ab = \sqrt a \times \sqrt b\]

- pokemon23

yes i got that

- pokemon23

now

- Akshay_Budhkar

ok now do the next one

- Akshay_Budhkar

\[\sqrt 45\]

- Akshay_Budhkar

go step by step

- pokemon23

|dw:1326249246307:dw|

- Akshay_Budhkar

no

- Akshay_Budhkar

why are they two roots?

- Akshay_Budhkar

*square roots

- Akshay_Budhkar

\[\sqrt 45 = \sqrt 9 \times \sqrt 5\]

- Akshay_Budhkar

- pokemon23

|dw:1326250193101:dw|

- Akshay_Budhkar

ok it is something like this
\[1/2 \sqrt 20 + \sqrt 45\]
=\[\sqrt 5 + 3 \sqrt 5\]
=\[4 \sqrt 5\]

- pokemon23

what happen to the 1/2?

- SamIam

akshay u r awesome xD

- pokemon23

how did you get |dw:1326250676815:dw|

- Akshay_Budhkar

ok
it is
\[1/2 \sqrt 20 \]
Now you have \[\sqrt 20 = 2 \sqrt 5\] so that multiplied by 1/2 gives you
\[\sqrt 5\]

- Akshay_Budhkar

and for \[\sqrt 45 = 3 \sqrt 5\]

- Akshay_Budhkar

LOL samlan , i am not awesome ..

- SamIam

ohhh don't blush try to accept the compliment

- Akshay_Budhkar
