A. 121 B. 100 C. 81 D. 64 E. 33

121 has only the factors 1, 11 (itself), and its square root, 11. So that's the correct answer. 100 has factors 1,2,4,5,10,20,25,50, and 100. So that's not it. 81 has factors 1,3,9,27, and 81, so that's not it. 64, has factors 1,2,4,8,16,32, and 64, so that's not it. 33 isn't even a square at all, and has factors 1,3,11, and 33, so that's not it.

A �simple square� is any integer greater than 1 that has only three positive integer factors�itself,its square root, and 1.
Which of the following is a simple square?
A. 121 B. 100 C. 81 D. 64 E. 33

factor each of the choices
121 = 11^2 = 1 * 121 = 1 * 11 * 11 (3 positive integer factors)
100 = 10^2 = 2^2 * 5^2 = 1 * 4 * 25 = 1 * 2 * 2 * 5 * 5
81 = 9^2 = 1 * 3 * 27 = 1 * 3 * 3 * 3 * 3
64 = 8^2 = 2^2 * 4^2 = 1 * 8 * 8 = 1 * 2 * 2 * 2 * 2 * 2 * 2
33 = 1 * 3 * 11
33 is not a product of a whole number times itself like the other choices

the answer is A. 121
