The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. You are trying to find the Hypotenuse. 

4*4 + 3*3 = x

16 + 9 = 25

25 divide by 2

= 5

X=5

Prove the divisibility of the following numbers: 5^23−5^21 by 24
vodka [1.7K]
5^23 - 5^21 = 5^(21+2) - 5^21
5^23 - 5^21 = 5^21*5^2 - 5^21*1
5^23 - 5^21 = 5^21*(5^2 - 1)
5^23 - 5^21 = 5^21*(25 - 1)
5^23 - 5^21 = 5^21*24
5^23 - 5^21 = 24*5^21
5^23 - 5^21 = 24*k

The original number is in the form 24k where k = 5^21, so this proves that the original number is a multiple of 24
