1) 511* log₇∛7 = 511*1/3 = 511/3 =170 1/3
2) 25^log₅√17 = (5^log₅√17)² = 17
3) log₃7*log₇81 = log₃7*4* log₇3 = 4
4) log₉√22 = 1/2*log₉22
сам пример: 1/2*log₉22/log₉22= 1/2
5) log₅√11 = 1/2* log₅11
сам пример: 1/2* log₅11 / log₅11 = 1/2
6)8^log₈3 = 3
сам пример: 18/3 = 6
7) 36^log₆√7 == (6^log₆√7)² = 7
