7*x - 1 ------- 5 e
/ 7*x - 1\ | -------| d | 5 | --\e / dx
Let .
The derivative of is itself.
Then, apply the chain rule. Multiply by :
The derivative of a constant times a function is the constant times the derivative of the function.
Differentiate term by term:
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 derivative of the constant is zero.
The result is:
So, the result is:
The result of the chain rule is:
Now simplify:
The answer is:
1 7*x - - + --- 5 5 49*e ------------- 25
1 7*x - - + --- 5 5 343*e -------------- 125
1 7*x - - + --- 5 5 79792266297612001*e ---------------------------- 95367431640625
