#127 Re: Help Me ! » Why Rationalize Infinite Limits » 2016-02-11 19:36:59
Hello MathisFun forummers,
I stumbles accross this excercise:
and I was thinking why should I rationalize it?
You are NOT rationalizing it; you are doing the reverse!
To rationalize is to eliminate the square-root signs in the denominator. Here you want to put the square-root signs back in the denominator!
And why do you that? Because it's the only way to solve limit problems of this sort!

(8 ^ 2) - [(1 * 3 + 4 + 5 + 7) + (9 + 6) * 0] = 45
I was hoping for 0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45.

It does not work if you split 26 as 18 and 8.
8 × 10 + 18 = 98
98/2 = 49 (not prime)

That's a physics pick-up line, not a math one.
A magnet goes into a bar and meets another magnet.
First magnet: I find you really attractive!
Second magnet: And I find you repulsive! Go away, we have nothing in common.
First magnet: Oh well, I guess we really are poles apart.
