I want help solving differential equations

This question

my sol

syms x y(t);

dsolve (diff(x,y) == exp^x/2*y);

problem

An error occurred during the following: exp

Insufficient input arguments.

Error Occurred: untitled (Line 2)

dsolve (diff(x,y) == exp^x/2*y);

Answer 1

[KSSV]

syms x y(x);
eqn = diff(y,x)==exp(x)/(2*y)

eqn(x) = 

sol = dsolve(eqn)

sol =
