Although t is known as Pythagoras' theorem and thus about 2500-2600 years old, considering Pythagoras lived between 5th and 6th century BC, it was known before this. There is evidence that the Babylonians of 20th to 16th century BC (some 1000 years before Pythagoras) knew it, making it about 3600-4000 years old.
8,000. each row's sum is the row # cubed. so the 20th row is 20*20*20 = 8000
It is neither. Prime numbers have two factors, which are 1 and itself. Composite numbers have at least 3 factors, which are 1, itself, and at least one other factor. One does not fit either definition, since the only factor of 1 is 1.(It used to be considered a prime number, but they changed the rules sometime in the mid-20th century.)
Here are the steps to solve that: * Take the last year of the 20th century (that would be 2000). * Divide that by 37. * Round the result downwards, to the nearest integer. That is, simply eliminate everything after the decimal point. * Multiply the result by 37.
