Find the derivative of the function.
y =
\(\displaystyle \displaystyle y \ = \ \sqrt {7x \ + \ \sqrt {7x \ + \ \sqrt {7x}}}\)
sqrt(7x +sqrt (7x +sqrt 7x))
I got 1/2(7x+(7x+(7x)^1/2)^1/2)^-1/2 (7+1/2(7x+(7x)^1/2)^1/2) (7+1/2(7x)^-1/2) (7)
sorry for the long and confusing way it's typed out. I'm not sure how to use symbols on here.
I double checked it and I think it is right but my hw program tells me it's wrong
Thanks in advance!
