1) logs 125 = logs 5³ = 3 logs 5 = 3⋅1 = 3
Ответ: 3
2) lg 0,01 = log₁₀ 0,01 = log₁₀ 10⁻² = -2 log₁₀ 10 = -2⋅1 = -2
Ответ: -2
3) 2log₂3 = log₂ 3² = log₂ 9
Ответ: log₂ 9
4) 32 log 37 = log 37^(3²) = log 37⁹
Ответ: log 37⁹
5) log₂ 68 - log₂ 17 = log₂ (68/17) = log₂ 4 = log₂ 2² = 2 log₂ 2 = 2⋅1 = 2
Ответ: 2
