Question

Assinale a propriedade valido :

a) log(a·b) = log a · log b
b) log (a+b) = log a + log b
c) log m · a = m · log a
d) log a ^{m} = log m · a
e) log a ^{m} = m · log a

Answer 1

E aí mano,

$a)~~log(a\cdot b)=loga\cdot b~~~(~~).\\\\ b)~~log(a+b)=loga+logb~~~(~~).\\\\ c)~~logm\cdot a=m\cdot loga~~~(~~)\\\\ d)~~loga^m=logm\cdot a~~~(~~)\\\\ \boxed{e)~~loga^m=m\cdot loga~~~(X)}.\\.$

Ótimos estudos mano!
