If t = e^x+2 then x =?
:
Do you mean: , or ?

Here is a method for each of them
:

using the nat log

the log equiv of exponents
(x+2)*ln(e) = ln(t)
we know the ln of e = 1 so we have
x + 2 = ln(t)
x = ln(t) - 2
Or

Subtract 2 from each side

using the nat log

the log equiv of exponents
x*ln(e) = ln(t-2)
we know the ln of e = 1 so we have
x = ln(t-2)
