|
Answer» -STEP EXPLANATION:For any NATURAL NUMBERS m>1,2m, m 2 −1, m 2 +1 forms a Pythagorean triplet.If we take m 2 +1=20, then m 2 =19The VALUE of m will not be an integer.If we take m 2 −1=20, then m 2 =21Again the value of m will not be an integer.Let 2m=20=>m=10∴2m=2⋅10=20m 2 −1 = 10 2 −1=99andm 2 +1 = 10 2 +1=101 |
