1. 5*3^n
A.5,15,45,135
B.15,30,45,60
C.15,45,135,405<-----
D.0,15,45,135
C looks good to me
To find the values of the expression 5 * 3^n, we need to substitute different values of n and calculate the result.
Let's start with n = 0:
5 * 3^0 = 5 * 1 = 5
Next, let's try n = 1:
5 * 3^1 = 5 * 3 = 15
Moving on to n = 2:
5 * 3^2 = 5 * 9 = 45
Finally, let's calculate n = 3:
5 * 3^3 = 5 * 27 = 135
Therefore, the correct option is C. 15, 45, 135, 405.
