Question

1. in pascals triangle, which row corresponds to the expansion of (a + b)^5? a. 6th row b. 5th row c. 4th row d. 7th row

Explanation:

Step1: Recall Pascal's Triangle property

The rows of Pascal's Triangle are numbered starting from 0. The coefficients of the binomial expansion \((a + b)^n\) are given by the \((n + 1)\) - th row of Pascal's Triangle.

Step2: Calculate the row number for \((a + b)^5\)

For \((a + b)^5\), using the property above, \(n=5\), and the row number is \(n + 1=6\).

Answer:

a. 6th row
