Nesting the value of variable in fsolve?

I am trying to nest a variable in function f(E). And thes variable, say V, is also a function of E.
For example,
V=exp(E(1))+E(2);
f=@(E) [E(1)+34*E(2); E(1)+(2+V*8)*E(2)]
The above code is hypothetical for better presentation for you.
If we run this kind of problem(I will fsolve it), it will show error such as E(1) and E(2) is not defined.
So if I code
syms E
then it will not deliver answer from function f.
What can you suggest when solving this problem?
ps. Again, above example is just an example. Thanks!
I love Matlab!!!

use
V = @(E)exp(E(1)) + E (2);
F = @(E)[E (1) +34 * E (2), E (1) + (2 + V(E) * 8) * E (2)]
OR
F = @(E)[E(1) +34 * E(2), E(1) + (2 + (exp(E(1)) + E(2))*8)* E(2)]

Thanks, it worked!
Could you answer my another question if you don't mind?
