Matemática, perguntado por catiathaynaraaf, 11 meses atrás

1) Dê o valor de:
a) Log12^1
b) Log0,3^0,3
c) Log10
d) 13Log13^7
e) Log2^2
f) Log65^1


GeBEfte: São todos log's na base 10.
GeBEfte: ? pq o simbolo " ^ " indica potencia
catiathaynaraaf: 1) Dê o valor de:
a) Log[12]1
b) Log[0,3]0,3
c) Log10
d) 13^[13]^7
e) Log[2]2
f) Log[65]1
catiathaynaraaf: d) 13^log[13]^7 ***

Soluções para a tarefa

a)

log_{12}1=x\\\\1 = 12^x\\\\12^0=12^x\\\\x=0

b)

log^{0.3}0.3=x\\\\0.3=0.3^x\\\\0.3^1=0.3^x\\\\x=1

c)

log10=log_{10}10\\\\log{10}10=x\\\\10=10^x\\\\10^1=10^x\\\\x=1

d)

13^{log_{13}7}=x\\\\Utilizando\;a\;propriedade:\;b^{log_{b}a}=a\\\\x=7

e)

log_{2}2=x\\\\2=2^x\\\\2^1=2^x\\\\x=1

f)

log_{65}1=x\\\\1=65^x\\\\65^0=65^x\\\\x=0
