i'm new to using matlab and i've been stuck on this for a while
i'm trying to calculate the value of V but i keep getting errors
syms V
y = 0.05;
k = 0.0806;
v = 90;
N = 4;
h = solve(y == 1/((1+k(V/v))^N),V)
Error using sym/subsindex (line 825)
Invalid indexing or function definition. Indexing must follow MATLAB indexing. Function arguments must be
symbolic variables, and function body must be sym expression.
Error in untitled2 (line 8)
h = solve(y == 1/((1+k(V/v))^N),V)

syms V
y = 0.05;
k = 0.0806;
v = 90;
N = 4;
h = solve(y == 1/((1+k*(V/v))^N),V) %multiplication sign missing
you only should change
h = solve(y == 1/((1+k(V/v))^N),V) --> h = solve(y == 1/((1+k*(V/v))^N),V)
