Efetue as operações abaixo:

a) log5 (22/3) + log5 (3/5) - log5 (4/5)

b) 2 log a – 3 log b – 2 log c + 1/3 log d

2) Se log3a – log3b = 3, calcule a/b

3) Se log2a = 2, log2b = 5 e log2c = 3, calcule o valor de

log2 (√ab/c2)

4) Se log 2 = 0,3010 e log 3 = 0,4771, log a = log 10a, calcule o valor de:

a) log 12.

b) log √32.

c) log 3√24/2.

d) 10x = 5.

e) 10x=1/4.
