64 is a perfect square number.

4000 is a square number but it is not the square of an integer so it is not a perfect square number.

A number multiplied by itself is a square number as for example 6*6 = 36

That depends on the series being squared. If we were using the whole numbers, for example, the fourth square number would be 16 (because it the fourth number made by squaring another number).

16

They are 9 and 16

No.

when you times the number by its value. for example if the number is 2. then to square it you would put 2 x 2. and for 8, it will be 8 x 8.

The answer is 256/the number .

Because there is no such thing as a squre number!50 IS a square number. It is the square of 7.0711, approx.7^2 = 49 and 8^2 = 64 and there is no whole number between 7 and 8 so 50 is not the square of an integer and so it is not a perfect square.

64 is a perfect square number.

Yes, it is a perfect square.

Yes, square of a number is always non-negative. e.g. (-2)2=4, (6)2=36, (21/2)2=2, etc.

4x-x^2 \ 2-square root 2 multiply 2+squre root x\ 2+squreroot x = 4x-x^2 (2+squre root x) \ 4_x = x(4-x) (2+squre root x) \ 4-x we will cancel the (4-x) so it will be x(2+squre root x) = (0) (2+squre root 0) =0

Both, 18^2 = 324 and 19^2 = 361
