Вычислите значение выражение log0,54+lg1/100 - log31/243 + lg0,01

1) log_0,5 (4) = log_2^ (-1) (2^2) = 2/-1*log_2 (2) = 2/-1*1=-2

2) lg (1/100) = log_10 (10^ (-2)) = - 2*log_10 (10) = - 2*1=-2

3) log_3 (1/243) = log_3 (3^ (-5)) = - 5

4) lg (0,01) = lg (1/100) = - 2

5) - 2 + (-2) - (-5) + (-2) = - 4+5-2=-1
