What is the difference between finding the square root of a perfect square and the square root of a non perfect square?
The square root of a non-perfect square may be irrational and therefore may not be easy to find. However, it need not be.For example, 2.25 is not a perfect square but 2.25 = 9/4 and both 9 and 4 are perfect squares. So sqrt(2.25) = sqrt(9/4) = sqrt(9)/sqrt(4) = 3/2 = 1.5. Not that difficult!
When you subtract one square number and the answer is 7 what are the two square numbers?
The two square numbers that satisfy the equation when one is subtracted from the other to give 7 are 9 and 2. Specifically, (9 - 2 = 7), where (9) is (3^2) and (2) is (1.414^2) when considering perfect squares. However, the perfect squares that work are (9) (from (3^2)) and (4) (from (2^2)), since (9 - 4 = 5). So, the two square numbers are (9) and (4).

A teenager's age increased by 2 gives a perfect square Her age decreased by 10 gives the square root of that perfect square She is 5 years older than her brother How old is her brother?
Answer: Her brother is 9 and she is 14. say she is 14, 14+2=16 a perfect square. 14-10=4 which is the square root of 16. So she is 14 and her brother is 9. (He is a perfect square too, by the way.)
