you must use the product rule combined with using the chain rule when you find each derivative.

y = (3x9)^9(x+2)^6 y1 = 9(3)(3x8)^8 (6)(1)(x+2)^5 y1 = 162 (3x9)^8(x+2)^5

yes you forgot to put an addition sign. the product formula is a*d/dx(b) + d/dx(a) * b

when you take the d/dx of the a and the b terms, that's when you execute the sign rule. this is an annoying question lol it will take some time to compute it all
