"squaring" any number means to multiply it times itself. Using your examples:
5 x 5 = 25 (You must have already memorized what 5 x 5 equals).
4 x 4 = 16 (Also must have already been memorized)
The prime numbers with square roots between 4 and 5 are 5 and 7.
25= 5*5 = (3*3)+(4*4)
9, the square of 3, and 4, the square of 2
There are 5 square numbers under 30: 1, 4, 9, 16, and 25.
They are 4 and 5
The first 5 square numbers are 1, 4, 9, 16, and 25.
4 and 9
9 - 4
4 and 9
-5 and -4 or 4 and 5
4 and 5
1, 4 and 144.
They can be both. For example, 4 x 4 = 16 5 x 5 = 25
5 and 4
4 and 5
A square is when a number is muliplied by itself. For example, 9 is the square of 3. 16 is the square of 4, and 25 the square of 5.
A number that has a square root has to be able to be the product of two of the same numbers. Example: 4 x 4 = 16 16 can have a square root because 4 and 4 are the same. 10 can't have a square root because 2 x 5 = 10, and 2 and 5 aren't the same numbers.
