What is the real value of x in the equation log(subscript 2)24-log(subscript 2)3=log(subscript 5)x?

I really cannot remember at all how logs work. I know the answer is 125 but have no idea how to get there. Thanks in advance.

  1. Two things to remember

    1. loga x = y is the same as ay = x

    2. Log A - Log B = Log (A/B) as long as the bases are the same

    so log(subscript 2)24-log(subscript 2)3=log(subscript 5)x

    log2(24/3) = log5 x
    log28 = log5 x
    3 = log5 x
    5^3 = x
    125 = x
