What is Pascal's Triangle?

Back

Pascal's Triangle is a triangular array of the binomial coefficients, where each number is the sum of the two directly above it. It starts with a '1' at the top, and each subsequent row corresponds to the coefficients of the binomial expansion.

How do you expand a binomial expression using the Binomial Theorem?

Back

The Binomial Theorem states that (a + b)^n = Σ (n choose k) * a^(n-k) * b^k, where k ranges from 0 to n. The coefficients (n choose k) can be found in Pascal's Triangle.

What is the 14th term in the expansion of (a + b)^n?

Back

The 14th term in the expansion of (a + b)^n can be found using the formula T(k+1) = (n choose k) * a^(n-k) * b^k, where k = 13 for the 14th term.

How do you find a specific element in Pascal's Triangle?

Back

To find a specific element in Pascal's Triangle, use the formula C(n, k) = n! / (k!(n-k)!), where n is the row number and k is the position in that row.

What is the significance of the coefficients in the expansion of a binomial?

Back

The coefficients in the expansion of a binomial represent the number of ways to choose k elements from n elements, which corresponds to the binomial coefficients found in Pascal's Triangle.

How do you calculate (4x + 3y)^4 using the Binomial Theorem?

Back

Using the Binomial Theorem, (4x + 3y)^4 = Σ (4 choose k) * (4x)^(4-k) * (3y)^k for k = 0 to 4, resulting in 256x^4 + 768x^3y + 864x^2y^2 + 432xy^3 + 81y^4.
