You can actually use either the product rule or the chain rule for this one. Observe:
• Method I:
y = cos² x
y = cos x · cos x
Differentiate it by applying the product rule:
The derivative of cos x is – sin x. So you have
—————
• Method II:
You can also treat y as a composite function:
and then, differentiate y by applying the chain rule:
For that first derivative with respect to u, just use the power rule, then you have
and then you get the same answer:
I hope this helps. =)

Answer:
1)
2)
3)
Step-by-step explanation:
To write logs of the form in their exponential form, you take the base b and put it to the power of x and then set that equal to a:
.
1. Here, b = 5, a = 25, and x = 2, so:
2. In this problem, b = 5, x = 2, and a = x, so:
3. Finally, here, b = b, a = 64, and x = 3, so:
Hope this helps!
