1/log (8) 0,75=log (0,75) 8

1/log (3) 0,75=log (0,75) 6

log (√2) 0,5=-2

log (0,75) 8-log (0,75) 6-2=log (3/4) 4/3 - 2=-1-2=-3

Перейдем к основанию 2

(log (2) 7+2) * log (2) 32/log (2) ∛2=5 (log (2) 7+2) : 1/3=15 (log (2) 7+2)

log (2) 7*log (2) 8/log (2) (2^1/5) = 3log (2) 7:1/5=15log (2) 7

15 (log (2) 7+2) - 15log (2) 7=15log (2) 7+30-15log (2) 7=30
