72 is rectangular.

a square number is with two products the same i.e. if multiply a number by itself you get a square number. e.g. 8 * 8 = 64, 9 * 9 = 81, 10 * 10 = 100 So 72 is not a square number.

The square root of 72 is an irrational number. Since 72 is not a perfect square, the decimal is endless. (just like the value of pi)

82 + 8 = 64 + 8 = 72

You take the square root of the number. If it is a perfect square, this will be a whole number. If it is not, it isn't a perfect square.

Because the square root of it is an irrational number

49 is 72 and is the closest square number to 50.

The two square roots of any positive number are the positive square root and the negative square root. The positive square root of 49 is 7, because 72=49, while the negative square root is -7, because -72=49.

No.

No, they are not.

49 equals 72, and the next square number is 82 = 64.

82+8 = 72

36

9

No because its square root is an irrational number

64 is the square of 8.

72/36 = 2

8

It isn't.

No. The closest square numbers are 72 = 49 and 82 = 64.

you cant have a square root of a negative number that is a math impossibility

To square a number you multiply it by itself. 7 x 7 = 49. or, 72 = 49.

No it is not. A Square number is one that can be expressed as the product of the same number twice. Ex: 49 is a square number 7 * 7 or 72

82 = 8 x 8 = 64 92 = 9 x 9 = 81 Since 72 is in between these answers 72 is not square. (The square root of 72 = 8.485281374...) There is no whole number which when multiplied by itself gives an answer of 72.

72 + 7 = 56
