FIND THE PGT TRIPLET-
WHOSE GREATEST MEMBER IS 101.(METHOD)
For any natural number m > 1, 2m, m2 − 1, m2 + 1 forms a Pythagorean triplet.
If we take m2 + 1 = 101
then
m2 = 101-1
m2 =100
m=10
The value of m is an integer.
Now,
m2 − 1 = 101
⇒ m2 = 101+1
⇒ m2 =102
The value of m is not an integer.
Let 2m = 101
m = 101/2
The value of m is not an integer.
Therefore, the Pythagorean triplets are 2 × 10, 102 − 1, 102 + 1 or 20,99 and 101.
