उत्तर

Let y = [log {log(logx)}]2 
Differentiating w.r.t. x, we get
`"dy"/"dx" = "d"/"dx"[log{log(logx)}]^2`

= `2.log{log(logx)} xx "d"/"dx"[log{log(logx)}]`

= `2.log{log(logx)} xx (1)/(log(logx))."d"/"dx"[log(logx)]`

= `2.log{log(logx)} xx (1)/(log(logx)). (1)/(logx) xx "d"/"dx"(logx)`

= `2.log{log(logx)} xx (1)/(log(logx)). (1)/(logx) xx (1)/x`

= `2.[(log{log(logx)})/(x.logx.log(logx))]`.
