Question

How to solve these?!!

Answer 1

a. Because logarithm is defined as an inverse of exponential, you can do this (it has a base of 3, and that's equivalent to saying the thing on your homework):

`3^y=x`

c. Same thing:

`3^y = x+1`
or:

`3^y-1=x`

e. Subtract 2 from both sides:

`3^(y-2) = x`

g. Subtract 2:

`3^(y-2) = x-1`
or:

`3^(y-2)+1=x`

i. Add 1, and subtract two:

`3^(y+1) -2 = x`

Those are all your answers.
