8^x+1=3

  • math - ,

    I have a feeling that you mean
    8^(x+1) = 3

    if not, then it would be real easy
    8^x + 1 = 3
    8^x = 2
    and we now the cube root of 8 is 2, so
    x = 1/3

    if 8^(x+1) = 3
    log both sides
    log 8^(x+1) = log3
    (x+1)log8 = log3
    x+1 = log3/log8
    x = log3/log8 - 1
    = appr -.47168
