If y=x^((x^(x))) then (dy)/(dx) is...

If `y=x^((x^(x)))` then `(dy)/(dx)` is

Text Solution

Verified by Experts

`y=""_(x)(x^(x))`
`"or "log y= x^(x) log x`
`"or "(1)/(y)(dy)/(dx)=(dz)/(dx)log x +(1)/(x)z("where "x^(x)=z)`
`"or "(dy)/(dx)=x^((x^(x)))[x^(x)(log ex)log x + x^(x-1)]" "(because(dz)/(dx)=x^(x) log ex)`
