Weird maths question

[From: ] [author: ] [Date: 11-06-06] [Hit: ]
we must multiply both the numerator and the denominator by the denominator.=3√2+8-O crapp... Ask Einstein, he might know.......
it says:
rationalise 6+√8 / √2
and the answer must be in the form of p√2+q
please tell me how to solve this! thank you!

-
multiply the top and bottom by √2
you then get (6√2 + √16)/2
which become (6√2 +4)/2
which is simple 3√2 + 2
There is your answer in p√2 +q form

in rationalising such equations, we must multiply both the numerator and the denominator by the denominator.
I don't have the square root sign on my phone so i would use this sign: |
(6+|8)*(|2) / (|2)*(|2)
=(6|2+|16) / (2)
=(6|2+4) / 2
Dividing through by 2
=3|2+2
This is of the form p|2+q where p=3 and q=2

-
multiply both numerator and denominator by √2
you would get
(6√2+√16)/2
simplifying
6√2+4/2
3√2+2
hence p=3 q=2

-
6+root 8= 6+root(2*2*2)= 6+2root(2)
6+2 root(2) /root (2)= 3 root(2) + 2

-
(6+8√2)/√2
=(3*√2*√2+8√2)/√2
=3√2+8

O crapp... Ask Einstein, he might know.
