Question

the cofficient of x in the expansion of (x+3)cube is​

Answer 1

Answer:

coefficient of x is 27 in the expression (x+3)cube

Answer 2

Step-by-step explanation:

Using (a+b)³ = a³+b³+3ab(a+b) , we get

(a + b)³ = x³ + 3³ + 3 × x × 3(x + 3)

= x³ + 27 + 9x² × 27x

Therefore, the coefficient of x is 27.
