Find the derivative of the following function: f(x)= 10x-3/5x +6x

Could you please insert parentheses to clarify the question?

10x-3/5x+6x
could mean
(10x-3)/(5x+6x) [??]
10x -(3/5x) + 6x [??]
[(10x-3)/5x] +6x [??}
etc.
There are no parentheses, that's what is confusing me also. The questions is exactly as written above.
Parentheses are implicit when it is printed in fraction form.
If it is printed as a fraction, your post is linearizing it (put on a single line) and it is necessary to insert parentheses around all numerators or denominators which contain more than one term.
