Answer:
No positive value of n
Step-by-step explanation:
we have to find out for how many positive values of n are both
  our-digit integers
 our-digit integers
Let us consider first cube
we get 4digit lowest number is 1000 and it has cube root as 10.
Thus 10 is the least integer which satisfies four digits for cube.
The highest integer is 9999 and it has cube root as 21.54
or 21 the highest integer.
Considering 3^n we get,
3^10 is having 5 digits and also 3^21
Thus there is no positive value of n which satisfy that both n cube and 3 power n are four digits.
 
        
             
        
        
        
Answer:
A) 2b+24x
Step-by-step explanation:
7b+3x-5b+21x
7b-5b+3x+21x
2b+3x+21x
2b+24x
 
        
             
        
        
        
F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.
