How many terms are in the binomial expansion of (3x + 5)9?
8, 9, 10, or 11?
We will use the concept of binomial expansion in order to find the number of terms.
Answer: Total no of terms in the binomial expansion of (3x + 5)9 = 10
Let us see how we will use the concept of binomial expansion in order to find the number of terms.
Explanation:
Let us expand our binomial expression that is (3x + 5)9
The number of terms in the binomial expansion of (x + y)p is given by
N = p + 1
Here, we have p = 9
Therefore, N = 9 + 1 = 10
Hence, there are 10 terms in the binomial expression of (3x + 5)9
