Homework Statement
y = x^(18x^-4)
Homework Equations
chain rule
dy/dx a^x = a^x ln a
The Attempt at a Solution
first i used the second equation from above to get
x^(18/x^4)*ln(x)
then i use the chain rule to get
x^(18/x^4)*ln(x)*(-72x^-5)
the computer program i am using is saying this is wrong and the only thing i can think of that is wrong is the fact I may not be able to use the one formula since x is not a constant but if this is true then i have no idea what to do
