Use properties of logarithm to expand the logarithmic expression as much as possible. Where possible, evaluate logarithmic expressions without using calculator. log4(4/x) = log4(4) - log4(x) = 1 - log4(x) Evaluate the expression without using a calculator. log7 1/root:7 log7(1/sqrt(7)) = log7(1) - log7(sqrt(7)) = 0 -(1/2)log7(7) = 0-1/2 = -1/2

Hope i can you!
