Question 1 is a known error that just got introduced into the new version of the gmatprep, many people have seen this.

Question 2 seems to be an error too, but you are probally the first person to report it.

As to the first one, I totally agree with you. I just picked some numbers for x and y that the product of those numbers is 1. Easiest example is x = 1, y = 1.

Result is $$\frac{8}{0}$$

If I use x = 2, y = $$\frac{1}{2}$$ because 2 * 1/2 = 1 I get the result of

$$\frac{25}{9}$$

$$\frac{2(2+\frac{1}{2})^2}{2(2-\frac{1}{2})^2}$$ = $$\frac{2(\frac{5}{2})^2}{2(\frac{3}{2})^2}$$ = $$\frac{2(\frac{25}{4})}{2(\frac{9}{4})}$$ = $$\frac{\frac{50}{4}}{\frac{18}{4}}$$ = $$\frac{50}{4} * \frac{4}{18}$$ = $$\frac{50}{18}$$ = $$\frac{25}{9}$$

The answer for question 2 should be D

statement 1: n = 2 ---> 3^(10) / 10 remainder is 9

statement 2: n can be any positive integer, and the remainder would still be 9

ok can i please know why u say that statement 2 is sufficent

the question stem does not define what n is (and it also does not talk abt what m is)

so why do u say that statement 2 is sufficent

therefore i think
statement 1 is sufficent

thanks
