Question

How many terms are there in the expansion of (3c - d)⁴ using Pascal's triangle?

A) 5
B) 6
C) 7
D) 8

Answer 1

There are 5 terms in the expansion of (3c - d)⁴ using Pascal's triangle.

Step-by-step explanation:

To determine the number of terms in the expansion of (3c - d)⁴, we can use Pascal's triangle. Each row of Pascal's triangle represents the coefficients of the terms in the expansion of (a + b)ⁿ, where n is the row number. In this case, we need to find the fourth row of Pascal's triangle. The fourth row is 1, 4, 6, 4, 1. Therefore, there are 5 terms in the expansion of (3c - d)⁴. Hence, the correct option is A) 5.
