A B N Expansion Math

I expanded a x n by taylor theorem also the result is same.

A b n expansion math. The first term is a n and the final term is b n. 1 4 6 4 1. 1 3 3 1. An bn an 1 b a n 1 i 0 b a i a an 1 1 b a n 1 i 0 b a i a b an 1 n 1 i 0 b a i a b an 1 an 2b an 3b2.

If you continued expanding the brackets for higher powers you would find that the sequence continues. A m n amn an 14. Progressing from the first term to the last the exponent of a decreases by 1 from term to term while the exponent of b increases by 1. Ab n a bn 15.

A b a 2ab b. There are n 1 terms. A3 b3 a b a2 ab b2 9. In elementary algebra the binomial theorem or binomial expansion describes the algebraic expansion of powers of a binomial according to the theorem it is possible to expand the polynomial x y n into a sum involving terms of the form ax b y c where the exponents b and c are nonnegative integers with b c n and the coefficient a of each term is a specific positive integer depending.

Write an a b b n and expand as 4 divides 24 4 is a factor of 24 we can write 24 4 6 similarly if a b is a factor of an bn then we can write an bn a b k where k is a natural number misc 4 if a and b are distinct integers prove that a b is a factor of an bn whenever n is a positive integer. You should notice that the coefficients of the numbers before a and b are. But the result is same if we expand a b n directly when n is a fractional or negative index or first expand 1 b a n and then multiply a n. Properties of the binomial expansion a b n.

Share a link to this answer. So a b a b. Let us start with an exponent of 0 and build upwards. It was a very appealing problem in the 17th and 18th centuries.

A n bn a b an 1 a 2b an 3b2 bn 1 10. Abn 2 bn 1 share. Exponents of a b now on to the binomial. It states a nice and concise formula for the n th power of the sum of two values.

When an exponent is 0 we get 1. A n 1 an an 1 a n 18. A b n an bn 16. Many other notable mathematicians have tackled the binomial theorem after newton.

Am a n am 12. In addition the sum of the exponents of a and b in each term is n. Am an am nif m n 1 ifm n 1 an m if m n a2r a6 0 13. A b a 3a b 3b a b.

If am anand a6 1 a6 0then. A b n. A b 0 1 exponent of 1. I was first informally presented by sir isaac newton in 1665.
