Answer:
No, 64/81 is not a perfect square.
Step-by-step explanation:
A perfect square is the product of an integer and itself.
For example: 6 and 6 is 36, 7 and 7 is 49.
In order to see if this number is a perfect squares, we just need to do the inverse, or find the square root of it.
so
[tex]\sqrt{64/81}[/tex]
now we have 8/9
8/9 is 0.889 which is not a whole number, and therefore 64/81 is not a perfect square.
