hey, i was wondering if you could show me how to rationalise the denomiators on a couple of these, in easy steps.
1
----
√ 2
√ 2
------
3√ 3
√ 43 - √ 23
-------------
√ 43 + √ 23
As in getting rid of radicals in the denominator?

cheers
√43 - √23 √43 - √23 43 - 2√(43x23) + 23 66 - 2√989
------------- x ------------ = ------------------------ = -------------
√43 + √23 √43 - √23 43 - 23 20
The math tag looks rather complex.
Why did the vector cross the road?
It wanted to be normal.
