First one

We are using these properties here  (these work the same with Ln)  :

Log (ab)  = Log (a) + Log (b)

Log (a/b)  = log a  - Log b

And

b log a  = log ab

So......

log3 (cd4)  =  log3 (c)  + log3 d4   =  log 3 (c)  + 4log 3 (d)    FALSE

(3/4)  ( Ln a + Ln b)   = (3/4)Ln ( ab)  = Ln (ab)3/4  = Ln (a3b3)(1/4)  = Ln 4√(a3b3)   TRUE

3 Ln e   - 2 Ln f    =  Ln e3  -  Ln f2   =  Ln ( e3 / f2)    TRUE

Second one.....

Remember that the inverse reverses  the coordinates

So....on the inverse graph we should have the points

(-6.4, 3)    (-2.6, 2)    (-1.2, 1)    (-1, 0)   ( -0.8, -1)   ( 0.6, -2)    (4.4, - 3)

Note that the graph should apear  to "fall"  from left to right  and the point (-1,0)  is on the graph

So    "A"  appears to be correct
