8 is a perfect cube; it is not a perfect square. Its Square root is a fraction and the square root of a perfect square is always an integer.
...you're thinking of 9...

The number 8 is not a perfect square because it is not classified as the product of two positive integers. The number 8 is classified as a perfect cube, however.


then you would have a perfect square



The square root of a perfect square is a whole number. Example sqrt(36) = 6 so 36 is a perfect square Example sqrt(25) = 5 so 25 is a perfect square Example sqrt(8)= 2.828 which is not whole so 8 is not a perfect square


No it is not, when you square it, it comes out to be 2.828427125...


factor the perfect square simplify the perfect root factor out the perfect cube simplify the perfect root √32 = √16 = √8◦2 = 4√2 move 8 out and simplify it to a perfect square


its a number that a different number goes into equallyfor example25 is a perfect square because 5 times 5 is twenty five. two of the same number multiply and get the perfect square8 times 8 is a perfect square7 times 9 is not

A perfect square has the condition that it must be any positive integer multiplied by itself. The closest perfect squares to 50 are 7*7 = 72 = 49 and 8*8 = 82 = 64 since 50 lies between 49 and 64, it must be it is not the square of a positive integer and, therefore, is not a perfect square.


Rational. It is a perfect square with answer exactly 8The square root of 64 is the integer 8 (8 x 8 = 64) so it is rational.


Is your brain damaged or something? It is 8.


Yes because 8 times 8 = 64


They are not, other that the fact that any perfect square is a non-negative and so is also a cube root of some non-negative integer (usually much larger). But -2 is a cube root (of -8), while -8 is not a perfect square.


How about 64 which is cube and square number because 4*4*4 = 64 and 8*8 = 64



It is: 8 because 8*217800 = 1742400 which is a square number
