The pattern is to divide by 3
486 ÷ 3 = 162
162 ÷ 3 = 54
  54 ÷ 3 = 18
  18 ÷ 3 = 6
The next number is 6
        
                    
             
        
        
        
Numerator 6x - 18 = 6(x - 3) 
Denominator x^2 - 5x + 6 = (x - 3)( x - 2)
 
        
                    
             
        
        
        
Answer:
6n²√3
Step-by-step explanation:
2√3n•√9n³ 
The above expression can be simplified as follow:
Recall 
√9 = 3
2√3n•√9n³ = 2√3n × 3√n³ 
Recall
m√a × n√b = mn√(a × b) 
Thus,
2√3n × 3√n³ = (2×3) √(3n × n³) 
2√3n × 3√n³ = 6√3n⁴
Recall:
√aᵇ = (aᵇ)¹/² = aᵇ/² 
√n⁴ = n⁴/²
√n⁴ = n²
Thus, 
6√3n⁴ = 6n²√3
Therefore,
2√3n•√9n³ = 6n²√3
 
        
             
        
        
        
You multiply the whole number by the denominator and then add the numerator and get 344/100 then simplify and then you get 86/25 then now its a improper fractions so turn it into a mixed number and its 3 11/25
