I think you misworded this question. If he buys 30 cups and puts four balls in each, then he would still have 30 cups.
Answer:
x2ˣ + 2ˣ
Step-by-step explanation:
<u>Points to remember</u>
(f * g)(x) = f(x) * g(x)
It is given that, f(x)= 2ˣ and g(x)=x+1
<u>To find the value of (f * g)(x) </u>
Let f(x)= 2ˣ and g(x) = x + 1
(f * g)(x) = f(x) * g(x)
= (2ˣ )* (x + 1)
= (2ˣ * x) + ( 2ˣ * 1)
= x2ˣ + 2ˣ
