Best ResponseYou've already chosen the best response.0To do these problems, I suggest utilize the chain rule as opposed to subbing in u into the original equation.

Best ResponseYou've already chosen the best response.0y=1/u^2, rewrite as y=u^2 to make it easier to differentiate. Using the chain rule. y'=2u*u'. Find u' by differentiating u=2x+3 with respesct to x. Sub in u and u' into y'=2u*u' and you have your solution.

Best ResponseYou've already chosen the best response.0I really messed that one up. I don't know what I was doing. Now I get the answer: 1/(2x3)^3

Best ResponseYou've already chosen the best response.0ok I am going to take it step by step now: 1st step is to get u^2 and 2

Best ResponseYou've already chosen the best response.0differentiate y to get y'=2u^3*u'. Substitute in u and u' and that's it.

Best ResponseYou've already chosen the best response.0yes then I get 2u^3 (2) then 2(2x+3)^3 (2) Am I good so far

Best ResponseYou've already chosen the best response.0ok then I get (4x6)^3 (2) then I am wanting to make (4x6)^3 into 2(2x3)^3 This is where I think I am making the mistake

anonymous

Best ResponseYou've already chosen the best response.0no you were already done. 2(2x+3)^3 (2) is correct because the 2 multiples with the 2 to become 4. I don't really follow what you did in your last response

Best ResponseYou've already chosen the best response.0your 3 exponent is only applied to 2x+3 and not the 2, there is no need to bring it down

anonymous

Best ResponseYou've already chosen the best response.0ok then it will be 4/(2x+3)^3
