Question:
y6 + 6 (x^2+4)6 = 9
6y5 .dy/dx . 6(x2 + 4)5 . (2x) = 0
6y5 .dy/dx = -6(x2+4)5 .(2x)
dy/dx = 6y5 / -6(x2 + 4)5 .(2x)
dy/dx = 6y5 / 12x(x2 +4)5
Although the answer is ment to have y5 as the numerator, not 6y5?
-------------
Another Q. [Simplifying result from product rule?]
Answer of the question:
6(x+4)5 .(x+2)7 + 7(x+2)6 . (x+4)6
It is possible to simplify the answer to
(x+4)6 (x+4)5 (13x+40)
Although, i don't see what to do to get this result.
Thanks in advance,
