Use properties of logarithms to expand the logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using a calculator.

Solution

a) log₆ ( 7*11) = log₆ 7 + log₆ 11 = 1.0860331325 + 1.3382908331 = 2.4243239656

            (as log_b(mn) = log_b(m) + log_b(n))

b)    log _d x⁹ = 9log_d x

(as log_b(mⁿ) = n · log_b(m))
