Question

Find the derivative.
y = π/(9x)^2

Answer 1

so would I first do the power rule on the bottom and make it 18x sooo Y=pi/18x?

Answer 2

i think you need to change the function to x^n form first

Answer 3

\[\large y = \dfrac{\pi}{(9x)^2}\]

Answer 4

\[\large = \dfrac{\pi}{81x^2}\]

Answer 5

\[\large = \dfrac{\pi}{81}x^{-2}\]

Answer 6

now it is ready for power rule ^^

Answer 7

take the derivative

Answer 8

or product rule? can we use that

Answer 9

is my math really off?
