    logs are pretty hard.
    the direction reads

    given that log 2 = 0.3010 and log 3 = 0.4771, state an equation you can use to find approximations of the logarithms of each of the following numbers without using a table. Then find the approximations.

    a. 4
    b. 8
    c. 1/2



    can someone please help me? :eek: :( :confused: :confused: :)

    Given log(2)=0.3010, you could try:



    Note the powers the powers of 2. 2^2=4, 2^3=8, etc.
