logarithms Solve the following equations 3^x2=6 Add 2 to both sides of the equation to start. Whatever operation you do to one side of an equation you must do to the other side as well. 3^x  2 + 2 = 6 + 2 3^x = 8 Changing to

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
