Question

Log de 0,000064 na base 5

Answer 1

log₅ 0,000064

=log₅ (10⁻⁶ *2⁶)

=log (10⁻⁶*2⁶) / log 5

=(log 10⁻⁶+ log 2⁶) / log 5

=(log 10⁻⁶+ log 2⁶) / log 5

=(-6og 10 + 6*log 2) / log 5

=(-6+ 6*log 2) / log 5

=-6 * (1- log2)/log 5

******log 5 = log 10/2  =log 10 - log 2 =1-log 2

=-6 * (1- log2)/(1-log 2)  

=-6
