Hmm. I see captcha's harder than that every day on numerous sites; with a lot of 'normal' captcha's you sit staring for minutes and then kind of gamble (like an OCR bot) to what it says. At least the formulas are clearly readable and there is a one correct answer to each of them, while this http://bit.ly/gKPgKH I cannot read (Google).
