Question

log de 1 na base 3 + log 0.01 na base 10

Answer 1

$\log_{3}1+\log_{10}0,01=$

$0+\log_{10} 10^{-2} =$

$-2.\log_{10} 10 =$

$-2.1 =$

$-2$

Answer 2

Log de 1 na base 3 + log 0.01 na base 10

Log 1 + log 0.01 ==>  0 - 2 ==> - 2
      3          10

Log 1  = x  ==> 3^x = 1 ==> 3^x = 3^0 ==> x = 0
       3

Log 0,01  = x  ==> 10^x = 0,01 ==> 10^x = 10^-2 ==> x = - 2
      10
