The answer is
Explanation:
According to the product rule,
This just means that when you differentiate a product, you do derivative of the first, leave second alone, plus derivative of the second, leave the first alone.
So the first would be
Okay, now the derivative of the first is
The derivative of the second is
Multiply it by the first and get
Add both portions together now:
If you multiply it all out and simplify, you should get
Explanation:
The product rule states that for a function,
The function
By applying the power rule, we see that;
Plugging
