7 gru 2023 · Many exam questions require expansion of an expression of the form (a+b) to the power of n or (a-b)^n. It can either be done 'long hand', wasting valuable ti...
4 wrz 2020 · Learn how to expand (a+b)^n by using Pascal’s Triangle and Binomial Expansion
To expand an expression using the distributive property, multiply each term inside a set of parentheses by each term outside the parentheses, and then simplify by combining like terms.

(A+B)^n and (A-B)^n formula expander to perform formula expansion for any n value or nth power of (A+B).
1 gru 2021 · If $n=st$ with $s>1$ odd, then we have $$ a^n+b^n=(a^t)^s+(b^t)^s $$ and you can use your "$n$ is odd" factorisation with $s$ instead. If $n$ is a power of $2$, there is no general method that I know of.
The triangle can be used to calculate the coefficients of the expansion of (a+b)n (a + b) n by taking the exponent n n and adding 1 1. The coefficients will correspond with line n+1 n + 1 of the triangle. For (a+b)6 (a + b) 6, n = 6 n = 6 so the coefficients of the expansion will correspond with line 7 7.
