    log-k(27) = -3/2

    If we make both sides of the equation an exponent over a base of "k", that and the log of the same base will cancel out leaving only the 27 inside. Now we have:

    27 = k^(-3/2)

    Now if we take both sides to the (-2/3) power, we get k by itself and our solution:

    k = 27^(-2/3)

    Turn the fraction form into a radical form:

    k = ∛(27^(-2))

    That simplifies to:

    k = 3^(-2)

    and simplifies again:

    k = 1/9

    Okay start with log base k 27=-3/2

    Next you want to get rid of base k so k^(-3/2)=27

    Now you want k to the power of one so (k^-3/2)^(-2/3)=27^(-2/3)

    K=27^(-2/3) solve for k and thats ypur answer
