Do you know how to expand it? \[ (x^31)^2 = (x^31)(x^31) \]

onegirl Group TitleBest ResponseYou've already chosen the best response.0
is that with the chain rule or?

onegirl Group TitleBest ResponseYou've already chosen the best response.0
you factor it right?

let me try to expand it

Now we will use distributive property of multiplication. \[ (x^31)(x^31) = x^3(x^31)1(x^31)=x^6x^3x^2+1=x^62x^3+1 \]

What is the derivative of \(2x^3\)?
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
and 6x^2 for 2x^3
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so it will be 6x^5  6x^2 ?
 one year ago

wio Group TitleBest ResponseYou've already chosen the best response.0
Yeah. You don't need to factor it.
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
so that's it?

onegirl Group TitleBest ResponseYou've already chosen the best response.0
okay can did we use the chain rule on this one or? no chain rule?
 one year ago

onegirl Group TitleBest ResponseYou've already chosen the best response.0
are u there?
