6
Step-by-step explanation:
The expounded binomial equation will looks like this;
₀⁶C x⁶y⁰ + ₁⁵Cx⁵y¹ + ₂⁴Cx⁴y² + ₃³Cx³y³ + ₄²Cx²y⁴ + ₅¹Cx¹y⁵ + ₀⁶Cx⁰y⁶
x⁵y (equivalent to x⁵y¹ -without the coefficient) in the expansion (x+y)⁶ is the 2nd value;
We can then refer to the Pascals triangle (attached) for the values of the coefficients. The second coefficient in row 7 of the Triangle is 6;
₁⁵C = 6
