Why do think this is true?

Since 1*0=99*0, do you consider this as proof of your assertion as well?

The log of your equation would beg to differ... EDIT: except you consistently used 1, not a variable. Duh! Mondays are rubbish. Anyway, shouldn't that read 2 = 99?

I dunno if it's a joke or not.
If you have a function f(x) such that [itex]f(x_0) \neq f(x_1)[/itex], for all [itex]x_0 \neq x_1[/itex]. Just in that case, you will have [itex]f(x) = f(y) \Leftrightarrow x = y[/itex]
Some function like :f(x) = 0x, f(x) = 1 ^ x, f(x) = x ^ 0 ([itex]x \in \mathbb{R} - \{ 0 \}[/itex]). You cannot have [itex]f(x) = f(y) \Leftrightarrow x = y[/itex]. Why? Because in that 3 examples:
[itex]\forall x, f(x) = const[/itex]

sin(0) = sin(2 pi)

Oh no! 2 pi = 0, meaning pi = 0, which means circles don't exist!

If only there was a flaw in the logic...

then:

LHS = 1*1 = 1
RHS = 1*1*1* ...(ninety five times) *1 = 1
LHS = 1 = RHS

How do you go from line (1) to line (2) ?
