Work: Find the solution of equation 400*(1+16*w*w) = w*w*(w*w+1)*(0.039*0.039*w*w+1) .
Question type: Equation
Solution:Original question:
| 400 | ( | 1 | + | 16 | w | w | ) | = | w | w | ( | w | w | + | 1 | ) | ( | 39 1000 | × | 39 1000 | w | w | + | 1 | ) |
| Left side of the equation = | 400 | × | 1 | + | 400 | × | 16 | w | w |
| = | 400 | + | 6400 | w | w |
| 400 | + | 6400 | w | w | = | w | w | ( | w | w | + | 1 | ) | ( | 39 1000 | × | 39 1000 | w | w | + | 1 | ) |
| Right side of the equation = | w | w | w | w | ( | 39 1000 | × | 39 1000 | w | w | + | 1 | ) | + | w | w | × | 1 | ( | 39 1000 | × | 39 1000 | w | w | + | 1 | ) |
| = | w | w | w | w | × | 39 1000 | × | 39 1000 | w | w | + | w | w | w | w |
| = | w | w | w | w | × | 1521 1000000 | w | w | + | w | w | w | w | × | 1 |
| = | w | w | w | w | × | 1521 1000000 | w | w | + | w | w | w | w | × | 1 |
| = | w | w | w | w | × | 1521 1000000 | w | w | + | w | w | w | w | × | 1 |
| 400 | + | 6400 | w | w | = | w | w | w | w | × | 1521 1000000 | w | w | + | w | w | w | w | × | 1 |
The solution of the equation:
w1≈-41.811263 , keep 6 decimal places
w2≈41.811263 , keep 6 decimal places
There are 2 solution(s).
