Try deleting line 9 and retyping it.

In between the n and the ( you have unicode character decimal 8289, which is known as "Function Application". It is an invisible character in most fonts
Note: e^4 should be written as exp(4) and ln(3) should be log(3)
There turn out to be relatively few programming languages that use ln to indicate logarithm.
