Logarithm!!! Select all of the following that are true statements: (a) log(2x) = log(2) + log(x) (b) log(3x) = 3 log(x) (c) log(12y) = 2 log(2) + log(3y) (d) log(5y) = log(20y) – log(4) (e) log(x) = log(5x) – log(5) (f) ln(25)

Prove that log a, log ar, log ar^2 is an a.p. Is the following below correct? Log ar^2  Log ar= Log ar  Log a hence applying laws of logarithm Log(ar^2/ar) = log(ar/a) Log and log cancels out and then crossmultiply hence a^2r^2
