Question 1165751
<br>
As you show them, we don't know what the functions really are.<br>
(1) Don't use the "√" symbol in your post -- we can't tell how much of the expression that follows is under the radical.  Or, if you use that symbol, then use parentheses.<br>
(2) Use parentheses where necessary -- e.g., x/(x+1) --> {{{x/(x+1)}}} instead of x/x+1 --> {{{x/x+1 = 1+1 = 2}}}<br>
