Never used this site so bear with me :D


Ok a question from my schoolbook:


Which of the following sets are Pythagorean triples?

Im pretty sure I got the first three right but not sure how to do this one at all:

3^2, 4^2, and 5^2.



Does the fact that there is already a 2 there mean I should square it twice??

HELP!!

Thanks!

A Pythagorean triple consists of 3 integers a, b, and c, where a^2 + b^2 = c^2. Hence 3, 4, and 5 are a Pythagorean triple, since 3^2 + 4^2 = 5^2. However, 3^2, 4^2 and 5^2 is NOT a Pythagorean triple, since 9^2 + 16^2 does not equal 25^2.

Sweet man, thanks. I was really messed up over this!

I thought I had the other two answers yest but now I rechecked and Im not sure.

The square root of 3, the square root of 4, and the square root of 5 are NOT Pyth. Triples correct? It equals out to 3+4=5 which is incorrect.

And for 1/3,1/4, and 1/5 I got 1/9+1/16=1/25 so that isn't one either?

That's right - these are NOT Pythagorean triples.
