Question

Is 5,7,9 a Pythagorean triplets? why? justify.

Answer 1

 

A "Pythagorean Triple" is a set of positive integers, a, b and c that fits the rule:

a2 + b2 = c2

then 5;7;9

5 square+ 7 square = 9 square
25+49 = 81
74 = 81

then 5;7;9 not Pythagorean triplet
.....

Answer 2

no it is not a pythogoran triplets
as
${5}^{2} + {7}^{2} = 25 + 49 = 73$
which is not equal to nine squared that is 81
