81 is a perfect square (9 x 9) but 80 is not. Hope this helps! :o)

No, the square root of 80 is 4 times the square root of 5.
However, 81 IS a perfect square (9*9=81)

No. √80=√16 * √5=4√5 5 is not a perfect square.

No two rational numbers that are the same multiplied make 80. A rational number is a number that can be expressed as a fraction in the form a/b. Of course, if you were asking to find a number squared that would make 80, we would be going into square roots. Hope this sparks your memory.

Since the square root of 80 is around 8.9, the answer is no. But 81 has a perfect square root of 9.
