Question

1. Вычислить:

а) log 2 1/8 ; б) log 0,0001; в) log 3 36 / log 3 6; г) 2 log 2 6- log 2 9.

Answer 1

a) log2 1/8=-3, b)-4, c)log6 36=2, d)2 log2 6 - log2 9=log2 6²-log2 9=log2 36 - log2 9=
=log2 (36/9)=log2 4 = 2 (tak kak 2²=4)

Answer 2

с) неверно: log 6 (36) = 2; d) верно

Answer 3

d) неверно: log 2 (36/9) = log 2 (4) = 2
