Binomial Estimation: Exercise

Using the first few terms of a binomial expansion to estimate a power: choosing the value of x, substituting into a given or a new expansion, brackets that don’t start with 1, percentage errors and approximations for small x · six levels, timed, full worked solutions

Make the bracket equal to the number you want to raise to the power, then substitute that value of x into each term. The smaller x, the better the estimate.
