Answer 1

check them out by seeing if the square of the longest side = sum of squares of the other 2 sides
eg is 96^2 = 72^2 + 64^2 ?

Answer 2

hint - its not that one

Answer 3

if you sqaure the last digit of each number you'll see which one its likely to be - then confirm it by doing the full multiplication

Answer 4
