how do i solve this equation?
log3x+log3(x-24)=4

  • math... precalculus -

    I will assume you mean log3 for all

    log3x+log3(x-24)=4

    log3 (x/(x-24)) = 4
    3^4 = x/(x-24)
    81 = x/(x-24)
    81x - 1944 = x
    x = 24.3

    Please help, I need help on these two problems. Solve the equation. log3(x − 16) = log3(9x) e^1 + ln(7) It appears on the homework that the ln(7) is written like this ^ln(7) but I am still stuck on it. Thanks!

    Use the Laws of logarithms to rewrite the expression log3(x^18*sqrt3(y12)) in a form with no logarithm of a product, quotient or power. After rewriting we have log3(x^18*sqrt3(y12))=Alog3(x)+Blog3(y) With the constant A=?
