Given that log 3 is approximately 0.4771 and log 2 is approximately 0.3010, use the properties of logarithms to find approximations for
a) log 1/4 = log(1)-log(4) = log(1) - log(2^2) = log(1)-2log(2) = 0-2(0.3010)
= -0.6020
------------------------------------------
b) log 30 = log(3*10) = log(3) + log(10) = 0.4771 + 1 = 1.4771
