Question 1 Report

Simplify log10 a $\frac{1}{3}$ + $\frac{1}{4}$ log10 a - $\frac{1}{12}$ log10a7

\frac{7}{6}

log10 a

zero

Answer Details

log10 a $\frac{1}{3}$ + $\frac{1}{4}$ log10 a - $\frac{1}{12}$ log10a7 = log10 a $\frac{1}{3}$ + log10 $\frac{1}{4}$ - log10 a $\frac{7}{12}$
= log10 a $\frac{7}{12}$ - log10 a $\frac{7}{12}$
= log10 1 = 0
