Hi Heureka, I am wondering if it can still be done easily if it is made more complicated ?In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomialAccording 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 positiveExpansion of ( )2 3− x 10 b) Use the first three terms in the binomial expansion of ( )2 3− x 10, with a suitable value for x, to find an approximation for 197 10 c) Use the answer of part (b) to estimate, correct to 2 significant figures, the value of 394 10
