 72 Why is $(2+\sqrt{3})^{50}$ so close to an integer? 32 When written in decimal notation, every square number has at most 1000 digits that are not 0 or 1. True or false? 12 I need help finding integral of $\frac{1}{x^2+x^4}$ 11 Why can't you square both sides of an equation? 10 Which is greater, $e^{\pi}$ or $\pi^e$?
