Simplify:
Note: The first letters next to log are the small letters.
16.) logr r
17.) logt t^4
18.) logb 1

16.) logr r
r^? = r
? = 1
17.) logt t^4t^? = t^4
? = 4
18.) logb 1
b^? = 1
b = 0
(Any number to the zero power is one) 
Thanks

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
