/ _____ \ / _____ \ \\/ 2*x - 5/*\\/ 2*x - 5/
(sqrt(2*x) - 5)*(sqrt(2*x) - 5)
Apply the product rule:
; to find :
Differentiate term by term:
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result of the chain rule is:
The derivative of the constant is zero.
The result is:
