<span style="background-color: #FFFF00; color: #000000; font-weight: bold"><font color=yellow>If you mean the square of a whole number, there is no solution. The only squares of whole numbers that differ by 5 are 2^2 =4 and 3^2 = 9. If you remove the restriction that it must be squares of whole numbers, there is an infinite number of solutions, since every positive number is the square of something (namely, the square root of that number). If you also allow complex numbers, even negative numbers are squares. In that case 9 = 3^2, 4 = 2^2, -1 = i^2 where i is the imaginary number representing the square root of -1.</font color=yellow></span hi>

Oh honey, there's no one "hardest math question in the whole world." Math is like a never-ending buffet of brain teasers! But if you're looking for a toughie, the Millennium Prize Problems are a good place to start. As for the answers, well, those are worth a cool million bucks each if you can crack 'em. Good luck, darling!
It really depends on who you're asking....
What is the value of pi.
Different people find different problems hard and so it is difficult to answer the question.
NO!!! But it does require a certain 'train of thought'. The word ' Mathematics /(maths); comes from Classical Greece, and means 'to learn'.
