Question

expanding binomials using pascals triangle
which row of pascals triangle would you use to expand (2x + 10y)^15?
row 15
row 25
row 0
row 12

Explanation:

Step1: Recall Pascal's triangle property

The coefficients for the expansion of \((a + b)^n\) are given by the \(n\)th row of Pascal's triangle.

Step2: Identify the exponent

In the binomial \((2z + 10y)^{15}\), the exponent \(n = 15\). So, we use the 15th row of Pascal's triangle.

Answer:

A. row 15
