Answer 2

Answer:

No, it is not an Pythagorian triplet.

Step-by-step explanation:

Take the smallest no. of the triplet

Now,

2m= 5

=> m= 2.5

1st no.

m^2+1

= 2.5^2+1 (Since, m = 2.5)

= 6.25+1

= 7.25

2nd no.

= m^2-1

= 2.5^2-1

= 6.25-1

= 5.25

Therefore, it is not a pythagorian triplet.
