Logarithms
Can someone please explain how to get the answers for these problems?

Simplify:
1.) e^3 + ln4

Express y in terms of x:
2.) log y = 1.2x-1
3.) ln y = 1.2x-1

TIA

1) is the expression $e^{3 + \ln{4}}$ ?
as you have it written, it is already simplified.

2) $y = 10^{1.2x - 1}$

3) $y = e^{1.2x - 1}$

btw, here's some free advice ...

change your user name. a name like that is not conducive to receiving help from those who help out on this board.
