Pierre de Fermat, a 17th century French lawyer, stated that any whole number can be written as the sum of four or less square numbers. For Example . 15 = 3(squared) + 2(squared) + 1(squared) + 1(squared)

    It's a nice theorem, but what is the question?

    Ok, so what the largest perfect square less than 95?

    10^2 is 100. What's 9^2?

    Then the largest perfect square that won't add up to over 95?

    so 9^2 + 4^2 + 1^2 is the answer?

    Close. 4^2 is 16. 81+16+1 is 98. So you have to use 3^2.

    Ok, 9^2 is 81, right? You can't use 4^2 since 81+16 is greater than 95. So 81+3^2 is 90. Now you have 5 left. How can you make 5 out of sums of squares?

    2^2 and 1^2

    So your answer is 9^2+3^2+2^2+1^2.
