No. Though every perfect square is a rational number, not every rational number is a perfect square. Example: 2 is a rational number but sqrt(2) is not rational, so 2 is not a perfect square.
Because anything times itself equals a perfect square and is considered that taking the square root of a perfect square (non negative numbers) which end result does not involve fractions but whole numbers is a perfect square. 1 x 1 = 1 sq.root(1) = 1 2 x 2 = 4 (Perfect square) sq.root(4) = 2
2 is a square number but, because it is not a square of an integer, it is not a perfect square.
no, 10 is not a perfect square. in order for a number to be a perfect square, you have to see if the numbers that are multiplied to get it are the same. for example: 2x2=4; 4 is a perfect square. 12x12=144; 144 is also a perfect square 5x2=10 or 10x1=10. 10 isn't a perfect square because 5 and 2, and 10 and 1, are different numbers.
No. to be a perfect square, you have to be able to square root it and get a whole number (NOT a decimal) the square root of 3 is 1.732. (1.7322 = 3) a perfect square is a number like 4 the square root of four is 2 (22 = 4)
