Question

Log [log (log x)] =0
5 9 2

(descriçao: log na base 5, log na base 9, log na base 2)

Answer 1

Olá

log5[log9(log2 x)]=0

Domínio:{x € IR:x>0}

=> log9 (log2 x)=5^0
=> log9 (log2 x)=1
=> log2 x =9^1
=> log2 x=9
=> x=2^9
=> x=512

Espero ter ajudado!

Answer 2

$\mathsf{\log_5{[\log_9{(\log_2{x})}]}=0}$

$\mathsf{\log_5{[\log_9{(\log_2{x})}]}=\log_5{1}}$

$\mathsf{\log_9{(\log_2{x})}=1}$

$\mathsf{\log_9{(\log_2{x})}=\log_9{9}}$


$\mathsf{\log_2{x}=9}$

$\mathsf{x =2^9}$

$\boxed{\mathsf{x=512}}$
