उत्तर

It is known that, if in a triplet of natural numbers, the square of the biggest number is equal to the sum of the squares of the other two numbers, then the three numbers form a Pythagorean triplet.

The given set of numbers is (4, 7, 8).

The biggest number among the given set is 8.

82 = 64; 72 = 49; 42 = 16

Now, 16 + 49 = 65 ≠ 64

∴ 42 + 72 ≠ 82

Thus, (4, 7, 8) does not form a Pythagorean triplet.
