First, you substitute x with 10 (recall that when -8x means -8 times x)
For the numerator (the top), you use PEMDAS (first multiply -8 and 10, then add 9):

Step-by-step explanation:
Assuming the following function we want to find the derivate of this function.
For this case we need to apply the chain rule given by the following formula:
On this case our function is and our value for u is
If we appply this rule we got this:
And now w can substitute and we got:
