I have this problem that I'm going to make the derivative of:
The next step i'm confused about:
I think I am overlooking something here...
How does the come to be squared? Underneath the 6000.
Hello, sara213!

How does the come to be squared? Underneath the 6000?
Are you sure you know your differentiation rules?
You can use the Quotient Rule,
. . which ends with "over the denominator squared".
Or use an easier way . . .
We have: .
Chain Rule: .
. . . . . . . . . .
When your numerator is a constant, as here, it is perhaps easier to think of the problem as having a negative exponent:
Now, that the derivative is
So you can think of the denominator being being squared as a result of either the quotient rule or simply the power rule: with n= -1 so that n-1= -1-1= -2.
Note that to finish you will need the fact that the derivative of is .
