Question

Solve logx = 6.4 by changing it to exponential form.

Answer 1

$\bf \textit{exponential form of a logarithm} \\\\ \log_a(b)=y \qquad \implies \qquad a^y= b \\\\[-0.35em] ~\dotfill\\\\ \log(x) = 6.4\implies \log_{10}(x)=6.4\implies 10^{6.4}=x\implies 2511886.43\approx x$

let's recall that when the base is omitted, "10" is implied.
