[ 1/1 Equation]
    Work: Find the solution of equation 100 = 90.7×（1+i）×（1+i） .
    Question type: Equation
    Solution:Original question:
     100 =
907
10
(1 + i )(1 + i )
    Remove the bracket on the right of the equation:
     Right side of the equation =
907
10
 × 1(1 + i ) +
907
10
 i (1 + i )
                                               =
