take antilog on both sides,which gives... 1 + log to the base b ( 1 + log to the base c ( 1 + log to the base d (x)))= a0.
 log to the base b ( 1 + log to the base c ( 1 + log to the base d (x))) = 0....take antilog again.
  1 + log to the base c ( 1 + log to the base d (x)) = b0.
log to the base c ( 1 + log to the base d (x)) = 0....take antilog again.
1 + log to the base d (x) = c0.
 log to the base d (x) = 0....take antilog again.
x=d0.
x=1....ANS.
REMEMBER...logax=0...on taking antilog it converts to.
x=a0....which gives 
x=1

loga(1+logb(1+logc(1+logd (x)=0
take antilog on both sides..
1+logb(1+logc(1+logd (x)=a0
logb(1+logc(1+logd (x)=0
take antilog on both sides
1+logc(1+logd (x)=b0
logc(1+logd (x)=0.
take antilog on both sides
1+logd (x)=c0
logd (x)=0
take antilog 
x=d0
x=1..ANS
[REMEMBER.........loga b=0...on taking antilog
b=a to the power of 0
b=1]
