Question

Sabendo que log 2=A e log 3=b, determine o valor de:
A)log 16
B)log 40
C)log 25,6
D)log 54
E)log 150

Answer 1

Bom dia

Sabendo que log(2) = a ,  log(3) = b, log(5) = c, log(10) = 1

determine o valor de:

A) log(16) = log(2^4) = 4log(2) = 4a
B) log(40) = log(2^2) + log(10) = 2a + 1
C) log(25.6) = log(256/10) = log(2^8/10) = 8a - 1
D) log(54) = log(2*3^3) = a + 3b
E) log(150) = log(2*3*5^2) = a + b + 2c
