    well you minus 8^6 to the other side and solve for x

  • math pre calc - ,

    If it is as she wrote it then
    3 x = 8^1 (2) - 8^1*8^5 = 8 (2-8^5)
    x = (8/3)(2-8^5)
    2 is negligible compared to 8^5
    x = -(8/3)(8^5)
    or about
    -87380

    I think she might mean
    8^(6+3x) = 16
    (6+3x) log 8 = log 16
