4sqrt.5

hey pokemon, try it yourself, thats how you will learnn , i will guide you

The whole point of this website actually...

u trying it man?

ok

|dw:1326248463156:dw|

hey i am here

ok

so far correct?

ok hello again pokemon

hello?

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

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

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

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

hey akshay is helping u out. He is good

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

you fine till here man?

Hey samlam thanks hehe

so lost?

ok what is that you don't get?

so the square root of 20 is the product of 5*4

square root of 20 is square root of 4*5

|dw:1326249125280:dw|

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

you fine with this.?

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

yes i got that

now

ok now do the next one

\[\sqrt 45\]

go step by step

|dw:1326249246307:dw|

why are they two roots?

*square roots

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

is that what you mean?

yes

ok go ahead :D

|dw:1326249569591:dw|

how is it going pokeman?

Go ahead yea. solve the whole thing now

its going great i supposed

YAHOO :DDDDDDDDDDDDD

ok pokemon i am still here :D go ahead

bye pokeman gonna go study see u around

ok

|dw:1326250193101:dw|

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

what happen to the 1/2?

akshay u r awesome xD

how did you get |dw:1326250676815:dw|

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

LOL samlan , i am not awesome ..

ohhh don't blush try to accept the compliment

thanks hehe :D

doesn't |dw:1326250913607:dw|

yes that is what i got.. \[4 \sqrt 5\]

i got more questions willing to help me

i heard hero got married LOL

seriously?

i dont to kaka LOL

u kidding?

kaka?

there was a party on twiddla

i missed out :(

ok thanks

|dw:1326251216009:dw|

oh u gotta first do foil Arrrrrgggghhhh

call hero to help u

|dw:1326251317018:dw|

isn't hero busy?

let me ask him

I don't want to bother him

ok go step by step, open the brackets

do we need to used foil?

(a+b)(c+d)= ac + ad + bc + bd

ok thanks

so use that in the thing above

|dw:1326251886970:dw|

yes

so when we multiply the answer is 3*7=|dw:1326251983779:dw|

ok it is
\[3 \times \sqrt 7 = 3 \sqrt 7\]

neither of the above u wrote is correct

|dw:1326252144798:dw|

perfect

thats it?

|dw:1326252489033:dw|

oh no you have to ADD them

|dw:1326252535016:dw|

u here?

ok

no problem

have a great day ahead! and meet you tomorrow.. we need to work a bit faster from now ok?

yes

am I correct?

1/2 \sqrt 20 = \sqrt 5

for the|dw:1326254978405:dw|

my answer is |dw:1326255046497:dw|

yes

yipeeeeeeeeeeeeeeeeeeee

rationalize the denominator and simplify the resulting fraction.

|dw:1326255280427:dw|

for this question mrs.math

|dw:1326255332662:dw|

yes that is correct

would the answer be 1

my mistake 7
