  1. log7 49(3√(x^5) )
    = log749 + log73 + log7 x^(5/2)
    = 2 + log7 3 + (5/2)log7 x

    it can't be evaluated unless you give me a value for x

    1) use the properties of logarithms to simplify the logarithmic expression. log base 10 (9/300) log - log 300 log 9 = 2 log 3 log 300 = log 3 + log 100 = log 3+2 I just do not know how to put these together now!
