[ 1/1 Equation]
    Work: Find the solution of equation (1+i)*(1+i)*(1+i) = 27 .
    Question type: Equation
    Solution:Original question:
     (1 + i )(1 + i )(1 + i ) = 27
    Remove the bracket on the left of the equation:
     Left side of the equation = 1(1 + i )(1 + i ) + i (1 + i )(1 + i )
                                             = 1 × 1(1 + i ) + 1 i (1 + i ) + i (1 + i )(1 + i )
                                             = 1(1 + i ) + 1 i (1 + i ) + i (1 + i )(1 + i )
                                             = 1 × 1 + 1 i + 1 i (1 + i ) + i (1 + i )(1 + i )
                                             = 1 + 1 i + 1 i (1 + i ) + i (1 + i )(1 + i )
                                             = 1 + 1 i + 1 i × 1 + 1 i i + i (1 + i )(1 + i )
                                             = 1 + 1 i + 1 i + 1 i i + i (1 + i )(1 + i )
                                             = 1 + 2 i + 1 i i + i (1 + i )(1 + i )
                                             = 1 + 2 i + 1 i i + i × 1(1 + i ) + i i (1 + i )
                                             = 1 + 2 i + 1 i i + i × 1 × 1 + i × 1 i
                                             = 1 + 2 i + 1 i i + i × 1 + i × 1 i + i
                                             = 1 + 3 i + 1 i i + i × 1 i + i i (1 + i )
                                             = 1 + 3 i + 1 i i + i × 1 i + i i × 1
    The equation is transformed into :
     1 + 3 i + 1 i i + i × 1 i + i i × 1 = 27

    
        i=2
    
    There are 1 solution(s).
