. Ania: Liczba log36 jest równa A) 2log18 B) log40 - 2log2 C) 2log4 - 3log2 D) 2log6 - log1

jaś: A) 2log 18 = log18² = log 324 --- odpada B) log 40 - 2 log2 = log40 - log2² = = log40 - log4 = log( 40/4) = log 10 = 1 --- odpada C)2log4 - 3log2 = log4² - log2³ = = log16 - log 8 = log(16/8) = log 2 --- odpada: D) 2log6 - log1= log6² - 0 = log 36 bo log1= 0 odp; D)
