1. ## calculating relative extrema

Can anyone help me in calculating relative extrema for the following:

f(x)=x^4 - V^45

i m stuck and need help, i would really appreciate. thanks

2. That is $x^{4}-v^{45}$?

3. yes

Solve f'(x) = 0. (Not really necessary since you should know what the graph of y = f(x) looks like).
