Answer: x = 1.1968729357 ; or, round to: 1.2 .
____________________________________________ You would take the "ln" (that is, "natural logarithm") of EACH side of the equation:
ln (e^4x) = ln (120);
______________________
Then continue:
4x ln e = ln 120
4x = ln 120 ; (since "ln e = 1")
then divide EACH side of the equation by "4", to isolate "x" on one side of the equation; and to solve for "x" ;
___________________________________
4x / 4 = (ln 120) / 4 ;
___________________________
x = (ln 120) / 4 ;
______________________________
Using a calculator:
_________________________________________________________
x = (ln 120) / 4 = (4.78749174278) / 4 = 1.1968729357
Answer: x = 1.1968729357 ; or, round to: 1.2 .

Volume of a sphere is 4/3pi∗r3. r is half the diameter.
Answer:
All real numbers except 
.
Step-by-step explanation:
The given function is
This is a rational function.
The domain of a rational function is all real numbers except values that will make the denominator zero.
The denominator of the given function is 
.
So the domain is all real numbers except
We solve for 
to obtain,
or 
.
Therefore the domain is all real numbers except .
