chain rule

[rustic marsh]

I can’t figure out why this answer makes sense. I can set up the chain rule but have trouble working it out

[quiet pilot]

It would be helpful to have the full question

[rustic marsh]

This is the full question but this specific part is just chain rule

[storm yew]

What i would get is 5/2*1/(sqrt(5x))

[storm yew]

Which can be simplified to what is here

you can either use a chain rule with the inner function being 5x and the outer function being sqrt(x) = x^(1/2)

you could also just factor out the 5 to get 5^(1/2) * x^(1/2) which is just the power rule with a constant factor

How?

[rustic marsh]

@quiet pilot do you know how he got that?

[quiet pilot]

Yes I believe I do

Here I wrote it down for you

Hope it makes sense

Ping me if you are still confused

@quiet pilot how does 5/5^(1/2)= 5(1/2)?
