Question

Find Pythagorean triplet whose smallest member is 4

Answer 1

Let us take 3 as m2-1

m2=3+1=4

m2=4 & m=2

so m2+1 =5 & 2m=4

 we get triplets as 3,4,5

Answer 2

Let 2m = 4

Then m = 2

Now,

$m {}^{2} \: \: \: m {}^{2} - 1 \: \: \: \: m { }^{2} - 1$

$2 {}^{2} \: \: \: \: 2 {}^{2} + 1 \: \: \: 2 {}^{2} - 1$

$4 \: \: \: \: 4 + 1 \: \: \: \: 4 - 1$

$4 \: \: \: \: 5 \: \: \: 3$

Thus, Pythagorean triplet is 4,5,3
