0, 1To be both a square and a cube, the number has to be a sixth power. You don't need to calculate though, since 06=0 and 16=1.The next 2 sixth powers are 26=64 and 36=729.

6 is defined as a perfect number because the sum of the divisors of 6 (1,2,3,6) sum up to 12, which is twice 6. Equivalently, the sum of its proper divisors (1,2,3) is the number itself.The origin of the phrase perfect number is unclear, but some theologians suggest it originates from the Bible, where God created the world in six days, with man on the sixth day.

sixth is an ordinal number already. six is the related cardinal number.

The sum of the 1st perfect number and 2nd perfect number is. . . 34!

I am pretty sure you can figure this out on your own. Raise different numbers to the square, until you get a 4-digit result. Similary, calculate the cube of different numbers, until you get a 4-digit number. If you want the SAME number to be both a perfect square and a perfect cube, then it must be a power of 6. In that case, just experiment raising different numbers to the sixth power, until you get a 4-digit number.

For a number to be a perfect square and a perfect cube, it must be a perfect sixth power. Now 36 = 729 is too small and 56 = 15625 is too large, leaving 46 = 4096 as the answer.

11 + 12 + 9 = 32
