Determine the value of each of the following logarithmic expressions. Do not change bases.

A) log8 4 <----- 8 is subscript

b)log 1/3 27 <---- 1/3 is subscript

  • math -

    let x = log8 4
    8^x = 4
    (2^3)^x = 2^2
    2^(3x) = 2^2
    3x=2
    x = 2/3

    do the 2nd the same way, let me know what you got

  • math -

    log(27) / log(1/3)
    log(3^3) / log(3^-1)
    3 log(3)/-1 log(3)
    -3
