[ 1/1 Equation]
    Work: Find the solution of equation 10/[w×w×(1+w×w)×(1+0.2w×0.2w)] = 100 .
    Question type: Equation
    Solution:Original question:
     10 ÷ ( w w (1 + w w )(1 +
1
5
w ×
1
5
w )) = 100
     Multiply both sides of the equation by:( w w (1 + w w )(1 +
1
5
w ×
1
5
w ))
     10 = 100( w w (1 + w w )(1 +
1
5
w ×
1
5
w ))
    Remove a bracket on the right of the equation::
     10 = 100 w w (1 + w w )(1 +
1
5
w ×
1
5
w )
    Remove a bracket on the right of the equation::
     10 = 100 w w × 1(1 +
1
5
w ×
1
5
w ) + 100 w w w w (1 +
1
5
w ×
1
5
w )
    The equation is reduced to :
     10 = 100 w w (1 +
1
5
w ×
1
5
w ) + 100 w w w w (1 +
1
5
w ×
1
5
w )
    Remove a bracket on the right of the equation::
     10 = 100 w w × 1 + 100 w w ×
1
5
w ×
1
5
w + 100
    The equation is reduced to :
     10 = 100 w w + 4 w w w w + 100 w w w
    Remove a bracket on the right of the equation::
     10 = 100 w w + 4 w w w w + 100 w w w
    The equation is reduced to :
     10 = 100 w w + 4 w w w w + 100 w w w

    The solution of the equation:
        w1≈-0.302160 , keep 6 decimal places
        w2≈0.302160 , keep 6 decimal places
    
    There are 2 solution(s).
