find the exact value of the expression

how do you start out ? i forgot all about logarithym.s please help with step my steps

  • calculus -

    This is not calculus.
    Log(base8) of 2 is what power x of 8 you must have so that 8^x = 2
    2 is the cube root of 8, so the answer is 1/3.

    2. logbase10(1.25)+logbase10(80)
    = log(base10)(1.25*80)
    = Log(base10)(100)
    What is the number x such that 10^x = 100 ?
