how do we get this? Formula wise? Especially in an excel spreadsheet. If I have the number 1244 for instance, how do I get its 13th root? Be smarter than...
If you're using Excel, =POWER(1244,1/13) will get you the answer you need. The POWER function raises the first number in parentheses to the power of the...

Hi, I ran across this while looking for something else. Prove that (x^2 + y^2) divided by 4 never leaves a remainder of 3. have fun, Cino [Non-text portions of...
... x=0,1,2 or 3 mod 4 So x² = 0,1,4, or 9 mod 4 In other words, x² = 0 or 1 mod 4 Similarly, y² = 0 or 1 mod 4 So x² + y² = 0+0 or 0+1 or 1+0 or 1+1 mod...
... Since 4x+3 = an odd number, one square is even and one is odd, an even number squared = 0 mod 4 while an odd number is of the form 2n+1 which when squared...

I'm afraid I'm gonna have to please sheer ignorance here and ask for an example. What number therefore full of 1's, or full of 1's and 0's, does, say, 13...

... wonderin' ... OK now the meat 2848 = 89*32 so there must be 5 zeros appended to the number to take care of the twos. 10^88 = 1 mod 89 since 89 is prime,...
