# differentiation watch

1. The (12^1/2) is just a constant, and so you don't differentiate it (like above)....you just keep it like it is, and differentiate the (x^1/2), which you have done correctly
2. lol sorry !!!! you have told me that like 1000000000's of time before .... sorry i just totally gorgot about the whole constant thing thank you soo much for helping me - sorry for being silly and forgetting things !
3. [QUOTE]dy/dx = (12^1/2) (1/2) (3^1/2)^-1/2

= root(3) / root(root(3)) = root(root(3))[QUOTE]
right... i get that(3^1/2)^-1/2 = root(root(3)
but how...........

oh no, oh no i get it I, GET IT- hurrah !
4. OH NO
root(3) / root(root(3)) = root(root(3))
how?

surely if you convert it into powers it =
3^1/2 divided by (3^1/2)^1/2
= 3^1/2 " 3^1/4
= 3^1/4
= fourth root of 3

or is that the same?
5. Hi. I have just woken up so all of this seems confusing. Can you tell me what exercise your question comes from and I shall explain it to you in full.

Newton.
6. i understand the entire think (thanks to you pple) the ONLY think is that root root 3 business in my last post
7. (Original post by franks)
OH NO

how?

surely if you convert it into powers it =
3^1/2 divided by (3^1/2)^1/2
= 3^1/2 " 3^1/4
= 3^1/4
= fourth root of 3

or is that the same?
root(root(3)) === 4th root of 3
8. === does mean = doesnt it ?!
9. yeah, i was just emphasising the identity
10. yeeeeeeeeeeey
FINALLY I HAVE GOT IT !!!

thank you thank you thank you !
