Question

which one of the following is a pythagoren triplet (2,3,4) (3,4,5) (4,5,6) (5,6,7)​

Answer 1

Answer:

Only (3,4,5) is a pythagorean triplet.

Let's assume that above 4 numbers are options A,B,C,D

Option A:

(2,3,4) . 2^2=4 , 3^2=9, 4^2 =16

4+9=13 not 16

Option C:

(4,5,6).4^2=16,5^2=25,6^2=36

16+25=41 not 36

Option D:

(5,6,7). 5^2=25,6^2=36,7^2=49

25+36=61 not 49

Option B:

(3,4,5). 3^2 =9,4^2=16,5^2=25

16+9= 25

Therefore (3,4,5) is a pythagorean triplet
