Log7log7√7(√7√7) find the value and solution of this

Begin from the most complex root over root... 

For the same base, allot every "7" their individual forces to which they are raised. On the off chance that a particular base is relegated, for example base 7, whole the power, acquire the power duplication with the log7(in the inside of first log). Continue to get a simplifoed arrangement as the log77 will be 1 and log1 will be 0.
