    16.) logr r
    r^? = r
    ? = 1

    17.) logt t^4t^? = t^4
    ? = 4

    18.) logb 1
    b^? = 1
    b = 0

    Thanks

  • Algebra help (correction) -

    Please forgive my sloppy typing. Here is what I meant. I hope you were able to figure it out anyway:

    17.) logt t^4
    t^? = t^4
    ? = 4

    18.) logb 1
    b^? = 1
    ? = 0
