Binomial theorem was used to expand a binomial in this maths tutorial on binomial expansion. Later on the method of binomial expansion for approximation was used to approximate the value of a decimal that was raised to the power 7. The first question required us to expand a binomial for three ascending powers of x. Binomial expansion formula was used to expand a binomial that was in the form (a+b)^7.
