basically you gotta factorise everything, and then take out terms out of the square root that are 'double'.

Can you show me how with a diff number?

like 484?

how do ytou find the other num bers?

10. apoorvk

Just find the prime factors. and then you can do the rest. do you get the concept now?

Um, not really...it's still kinda confusing..

but thanks anywayt..

square root means the reverse of squaring. suppose 6 squared is 36. so then square root of 36 is 6. and since squaring basically means multiplying a no. by itself, square rooting means if a no. has a single factor twice, we count it only once while square rooting. and the factors that are single, are left alone inside the root. Have you seen the movie "Harold and Kumar"? 'cause this might help..

oohh ok! Thanks! And no, I haven't seen it

Hmm. here if I can find a link to the discussion thread, scroll read the poem from the movie, that may just help you understand the topic better ;)
