Which of the following is a perfect square? A. 169 B. 154 C. 279 D. 115
2 answers:
169 is a perfect square because 13*13 equals 169. You can find that this is the correct answer by taking the square root of the other values and seeing that the result is not whole numbers.
I recommend learning all of the perfect squares up to 25 as they will be very useful in Algebra/Calculus. Below I have attached a reference chart that you can use to learn them. The highlighted numbers are the perfect squares.
