Solution - Simplification or other simple results

1 / (2^{2} * 5^{2} * 13^{2}) = 0.00006

1/(2^2*5^2*13^2)=0.00006

Changes made to your input should not affect the solution:

(1): "^-2" was replaced by "^(-2)".

Step 1 :

 1.1     130 = 2•5•13

(130)^-2 = (2•5•13)^(-2) = (2)^(-2) • (5)^(-2) • (13)^(-2)

       1                
  ——————————— = 0.00006 
  (2²•5²•13²)
