Question

which of the following are not Pythagorean triplets
A)3,4,5
B)8,15,17
C)5,12,13
D)2,3,4​

Answer 1

Sp Pythagorean triplet is a triplet which can be represented in form of

(2n)²-(n²-1)²=(n²+1)²...(1)

Step-by-step explanation:

if 2n = 2

n=1

n²-1=1²-1

n²-1 =0

n²+1=2

But n²-1=0 is not equal to 3

n²+1=2 which is not equal to 4

Hence 2,3,4 is not a Pythagorean triplet.
