Question

log1/28=-3

Answer 1

If you want to know if your equation/statement is true or not, then these are the rules you need.

1) \(\large\color{black}{ \frac{\LARGE 1}{\LARGE a}=a^{-1}}\)

2) \(\large\color{black}{ \log(a^b)=b\times \log(a)}\)

3) \(\large\color{black}{ C=C\times \log_a(a)=\log_a(a^C)}\)

Answer 2

\(\large\color{black}{ \log(\frac{1}{28}) =3 }\)

\(\large\color{black}{ \log(\frac{1}{28}) =3\times \log(10) }\)

\(\large\color{black}{ \log(\frac{1}{28}) =\log(10^3) }\)

\(\large\color{black}{ \log(\frac{1}{28}) =\log(1000) }\)

tell me is your statement true or not?
