Question

Solve log x = 4. Ox=4 O x = 40 Ox= 1,000 Ox= 10,000

Answer 1

Hi there! :)

Answer:

$\huge\boxed{x = 10,000}$

Given:

$logx = 4$

The given expression is a logarithm with a base of 10, therefore we can rewrite this as:

$10^{4} = x$

Evaluate:

$x = 10,000$

Answer 2

Answer:

$\huge\boxed{x=10,000}$

Step-by-step explanation:

$\text{We know:}\\\\\log_ab=c\iff a^c=b,\ a>0,\ a\neq1,\ b>0,\ c\in\mathbb{R}\\\\\log a=\log_{10}a\\\\=============================\\\\\text{We have:}\\\\\log x=4\Rightarrow\log_{10}x=4\iff10^4=x\\\\x=10,000$
