<h3>What is the power rule for a derivative?</h3>
Suppose we have a power function given by:

The derivative of the function is given by:

Item a:
The function is:

Then the derivative is:

When x = 2, the derivative is:

Item b:
The function is:

Then the derivative is:

When x = 3, the derivative is:

I think it's the last one Which is 160° :)
So 4/5 times "something" = 32.
That means that something = 32 / (4/5) = 40.
To turn this multiplication around, it helps to think about 2 * 3 = 6, how would you write 3 = ?. You quickly :"see" that it should be 3=6/2.
