Good. Lets do the next two.
The first three terms of the binomial expansion ((1 + x) to the power n) are 1,−9, 297/8
respectively. What is the value of n?
(a) 5
(b) 8
(c) 10
(d) 12

Given log(p)x = a and log(q)x = b, the value of log(p/q)x equals
(a) ab/(b - a)
(b) (b - a)/ab
(c) (a - b)/ab
(d) ab/(a - b)
log(p)x stands for log of x with base p. And similarly read log(q)x & log(p/q)x.
