Jambmaths question:
Evaluate $\frac{{{81}^{\tfrac{3}{4}}}-{{27}^{\tfrac{1}{3}}}}{3\times {{2}^{3}}}$
Option A:
1
Option B:
$\tfrac{1}{8}$
Option C:
3
Option D:
$\tfrac{1}{3}$
Jamb Maths Solution:
$\frac{{{81}^{\tfrac{3}{4}}}-{{27}^{\tfrac{1}{3}}}}{3\times {{2}^{3}}}=\frac{{{3}^{4(\tfrac{3}{4})}}-{{3}^{3(\tfrac{1}{3})}}}{3\times 8}=\frac{{{3}^{3}}-3}{3\times 8}=\frac{27-3}{24}=\frac{24}{24}=1$
