Express (16- 4x)^3/2 in the form a(1+bx)^3/2, where a and b are real numbers. Find the values of a and b. The binomial expansion (16-4x)3/2 in ascending powers of x up to the term in x is 64 + ax + cx² + dx³+.., find the values of a, c and d. State the interval of x for which the expansion is valid. Hence, by substituting x=2 into the expansion, show that √2 isapproximately equal to 64/45​
