Do you know how to work with square roots?

Answer 3

dont have a calculator on me

Answer 4

Okay, what you are going to do is plug each number into the a^2+b^2=c^2 equation and see what checks out. Give me a second and I'll help you out a little more.

Answer 5

So, when you plug every equation into the calculator, you'll find that the only one that doesn't check out evenly is option d. The square of C is NOT equal to the squares of a and B, making it not suitable to be a pythagorean triple.
