    The equation given needs to be rpresentd as a single number. How would you do it? I just simplified the equation, got the dcimal numbr and added the digits.

    The sum of digit is 9.

    3333^3 - sum of this result is 3.
    33333 - sum of this number is 6

    total 9.

    Explanation :

    3333 X 3333 X 3333 + 33333 - This is the given equation.

    3333 X 3333 = result should be 9.

    if you multiply any number with 9 the sum of digits is multiplying remainnig number sum. here 3+3+3+3 = 3.

    So finally 3+6 = 9.
