 are identical up to eight decimal places.
The approximate real root is x ≈ 1.32471795
∴ x = 1.32471795
 
        
             
        
        
        
Answer:
90 red pens
Step-by-step explanation:
we need to find the least common multiple of the numbers 3 , 5 , 6 , 9
6 = 2 × 3
9 = 3²

The number 90 can be divided into 3 ,5 ,6 ,9 with no remainder 
Therefore the pack must have 90 pens or a multiple of 90
For example 180 , 270 ...
