Step-by-step explanation:

  • [tex](7x)^x=7^{7^7}[/tex]

log both sides:

  • [tex]log_7(7x)^x=log_7(7^{7^7})[/tex]
  • [tex]xlog_7(7x)=7^7[/tex]
  • [tex]x(1 +log_7x) = 7*7^6[/tex]
  • [tex]x(1 +log_7x) = 7^6(1+6)[/tex]
  • [tex]x(1 +log_7x) = 7^6(1+log_77^6)[/tex]

Compare both sides to get:

  • [tex]x=7^6[/tex]

or

  • [tex]x=117649[/tex]
