# How do you solve log- m+2 = 4 ?

Apr 19, 2018

$m = - 100$

#### Explanation:

I am assuming that we have:

$\log \left(- m\right) + 2 = 4$

$\implies {\log}_{10} \left(- m\right) = 2$

Remember that:

If ${\log}_{a} \left(b\right) = c$, then $b = {a}^{c}$

$\implies - m = {10}^{2}$

$\implies - m = 100$

$\implies m = - 100$
