Question

sabendo que log2= 0,3010 e log3= 0,4771 calcule log 8 ,log5, log2/100, log108

Answer 1

Log 8

= Log 2³
= 3 Log 2
= 3 * 0,3010
= 0,9030

Log 5

= Log 10/2
= Log 10 - Log 2
= 1 - 0,3010
= 0,699

Log 2/100

 = Log 2 - Log 100
= 0,3010 - 2
= -1,699

Log 108

= Log 2² * 3³
= 2 Log 2 + 3 Log 3
= 2 * 0,3010 + 3 * 0,4771
= 0,6020 + 1,4313
= 2,0333
