G(f(x))= (7x+8)^4
g(f(x))= (7(0)+8)^4
 =(0+8)^4
 =8^4
 =8•8•8•8
 =4,096
        
                    
             
        
        
        
The Lowest common multiple of 22 and 44 would be 22 because each of the numbers are divisible by it. So 22 / 22 = 1 and 44 / 22 = 2
        
             
        
        
        
The answer to your question is 42. The rule is 5 or more go up 1 . If the number is 4 les stay where it is. hope this help.
