Question

log x = log 1000+ colog 10

Answer 1

$logx=log1000+colog10\\ logx=log1000-log10\\ logx=3-1\\ logx=2\\ x=10^2\\x=100$

Explicação passo a passo:

$\mathsf{log\:x = log\:1000 + colog\:10}$

$\mathsf{log\:x = log\:1000 + log\:\dfrac{1}{10}}$

$\mathsf{log\:x = log\:1000 + log\:10^{-1}}$

$\mathsf{log\:x = log\:10^3.10^{-1}}$

$\mathsf{log\:x = log\:10^2}$

$\boxed{\boxed{\mathsf{x = 100}}}$
