Jambmaths question:
If ${{\log }_{3}}18+{{\log }_{3}}3-{{\log }_{3}}x=\log 3,$ find x
Option A:
0
Option B:
3
Option C:
2
Option D:
1
Jamb Maths Solution:
$\begin{align} & {{\log }_{3}}18+{{\log }_{3}}3-{{\log }_{3}}x=3 \\ & {{\log }_{3}}\frac{18\times 3}{x}=3 \\ & {{\log }_{3}}\frac{54}{x}=3 \\ & \frac{54}{x}={{3}^{3}} \\ & \frac{54}{x}=27 \\ & x=\frac{54}{27}=2 \\\end{align}$
