What is differentiation of 1÷root x​

Let f(x)=1√x , then y=1uandu=x12 , since √x=x12 . This means we have to differentiate both functions and multiply them.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
