Question

1 - Sendo log 2 = a; log 3 = b e log 5 = c e log 7 = d, determine:

a) log 42

b) log 60

c) log 36

Answer 1

Sendo log 2 = a; log 3 = b e log 5 = c e log 7 = d, determine:

a) log 42 = log(2.3.7) ==> log2+log3+log7 ==> a + b + d

b) log 60 =  log(2².3.5) ==> 2log2 + log3 + log5 ==> 2a + b + c

c) log 36 =  log(2².3²) ==> 2log2 + 2log3 ==> 2a + 2b + d
