How many terms are in the binomial expansion of (3x + 5)9?
We will be using the concept of binomial expansion for finding the number of terms.
Answer: There are 10 terms in the binomial expansion of (3x + 5)9.
Let us see how we will use the concept.
We know that the number of terms in any binomial expansion of (x + y)n is given by:
Number of terms (N) = n + 1
So, in the given binomial expansion (3x + 5)9, we have:
n = 9
Therefore, N = 9 + 1 = 10
