Question

log7 √7 me responda

Answer 1

log[a] b =log b/log a

log[a] a = log a/log a =1

log a^b = b* log a

log √a = log a^(1/2) = (1/2)* log a

##################################

log₇ √7  = log √7 / log 7  =(1/2)* log 7/ log 7  =(1/2) é a resposta

Answer 2

Vamos lá :

$log~_{7}~\sqrt{7} = x \\ \\ 7^{x} = \sqrt{7^{1}} \\ \\ 7^{x} = 7^{ \frac{1}{2} } \\ \\ x = \dfrac{1}{2}$

Logo ..$log~_{7}~\sqrt{7} = \dfrac{1}{2}$

Espero ter ajudado !!!
