Question

Find the derivative of f(x)=[18^{0.5t}+2\]

Answer 1

well its actually zero... since there is no x on the right hand side of the equation.

perhaps it should be

\[f(t) = 18^{0.5t} + 2\]

Answer 2

Find the derivative of f(x)=[18e ^{0.5t}+2\]

Answer 3

well then its zero... simple as that...

you are differentiating a constant as there is no term on the right hand side that involves x.
