For the value of x-2 a. Use it to calculate a value for ex and the value of your binomial expression in question 7 b. If possible use the first 5 terms of your binomial expansion from question 7 to estimate a value for the binomial expression. If not possible explain why. c. If possible use the first 4 terms of your Maclaurin series to estimate a value for ex. If not possible explain why. d. Where possible compare your estimated and calculated answers to the preceding parts. Explain are there any advantages to the estimated process.Use the binomial theorem to expand the binomial expression (1 + x) , and state the range of values of x for which the expansion is valid
