log2(64) + log3(1/81)
log5(25) - 2 log3 (pierwiastka z trzech) + log1/3 (27)
log2(64) + log3(1/81) = log2(2^6) + log3(3^(-4)) = 6 + (-4) = 2
log5(25) - 2 log3 (pierwiastka z trzech) + log1/3 (27) = log5(5^2) - log3 (pierwiastka z trzech)^2 + log1/3 ((1/3)^(-3)) = 2 - log3 (3) + (-3) = 2 - 1 + (-3) = 1 + (-3) = -2
log₂64 + log₃ 1/81 =
= log₂2⁶ + log₃3⁻⁴ =
= 6 - 4 =
= 2
log₅25 - 2log₃√3 + log₁/₃27 =
= log₅5² - log₃(√3)² + log₁/₃ 3⁻³ =
= log₅5² - log₃3¹ + log₁/₃ 3⁻³ =
= 2 - 1 -3 =
= 2 - 4 =
= -2
