Question

The coefficient of x in expansion of (x+3)^3is

Answer 1

Answer:

27

Step-by-step explanation:

(x+3)^3 = x^3 + (3)^3 + 3(X)(3)(X+3)

= x^3 + 27 + 9x^2 + 27x

As you can see that their is only one term containing x which is 27x and the coefficient of x in 27x is 27.

Therefore, 27 is the answer...
