Can anyone help me to find the first derivative f’(x) of the following functions?

a) $f(x)=x^4+3x^2+7x-10$

b) $f(x)=\frac{8}{x^3}$

Thanks

a) $f(x)= x^4+3x^2+7x-10$

the first derivative is:
$f'(x)=4x^3+6x+7$

b) $f(x)=\frac{8}{x^3}=4x^{-3}$

the first derivative is:
$f'(x)= -12x^{-4}=-\frac{12}{x^4}$

Hope these help!!
