f(n) = 2 * 3 ^ (n-1) f(2) = 2 * 3 = 6 f(5) = 2 * 3 ^ 4 = 2 * 81 = 162 f(1) = 2 * 3 ^ 0 = 2 * 1 = 2

ab = 21

A=3 b=7

2

2√6

Square both sides and you will get: x+1/x+2=16 and then subtract 2 from both sides and you will get: x+1/x=14. So the answer is A,14. (Use (a+b)^2=a^2+b^2+2ab)

(1/3+1/3+1/3):1/27=1:1/27=1*27/1=27

XrootX=27 is X squared times X=729 Xcubed=729 Cubed root of Xcubed= cubed root of 729 X=9
