for 2:30 do you just do trail and error until you find a counter example?
Yeah, that seems to be the best approach for this!

For question three we can also use a sqaure root of 2 and a square root of 8 ... giving us 16, square root of 16 is 4.. therefore it disproofs the statement.
Correct!
Isn’t 41 considered a prime number as it only has two factors, 1 and 41?
Yes, but we are looking at 41^2, which is 41 x 41, so isn't a prime number!
I will be honest, mathematical proof is a tad difficult from chapters 1-7 aha
