Oblicz : a)log8 (ósemka mała na dole)4+log(8 na dole)2= b)log3 (3na dole)36-log3(3 na dole)4= c)2log12 (12na dole)2=log12(12na dole)3= POMOCY POTRZEBUJE NA JUTRO

Answer 1

Oblicz :

a)log8 4 + log8 2= log8 (4 * 2) = log8 8 = 1

b)log3 36 - log3 4= log3 (36 : 4) = log3 9 = log3 3^2 = 2log3 3 = 2 * 1 = 2

c)2log12 2 + log12 3= log12 2^2 + log12 3 = log12 (4 * 3) = log12 12 = 1

Answer 2

a)

b)

c)
