Question

Help!!!! Is there a shortcut to expand (sqrt{c} + sqrt{d})^8 ????? PLease Help!!!!!

Answer 1

binomial theorem?

Answer 2

pascal's triangle works too...

Answer 3

um.. what's binomial theorem?

Answer 4

uh nevermind..i dont get it either lol..it's a higher algebra

Answer 5

it would work it would just expand (c^(1/2) + d^(1/2))^2

Answer 6

ok.. thx to both of you :)

Answer 7

though that is raised to 8 @corey89

Answer 8

which is pretty bloody manually @_@

Answer 9

http://en.wikipedia.org/wiki/Binomial_theorem this will help alot, the anwser will be long. You are correct about the 8

Answer 10

ok.. i am a simpleton.... thx, it really helps... i had no idea there was such a thing called binomial theorem or pascals triangle!

Answer 11

(a+b)^8 = (a+b)(a+b)(a+b).....(a+b) up to 8 times. Expanding all that is a pain. So, some math geeks created an approach to memorize the pattern for any power. In this case, it gets nastily BIG in terms of the ultimate expression.

Answer 12

c^4 + 8c^7/2*d^1/2 + 28c^3*d + 56c^5/2*d^3/2 + 70c^2*d^2 + 56c^3/2*d^5/2 + 28c*d^3 + 8c^1/2*d^7/2 + d^4

Answer 13

There you go....that I believe is right. :)

Answer 14

lol =)) who could memorize that haha
