Question : 24

Total: 50

Evaluate

\frac{ \frac{27^{1}}{3} - \frac{8^{2}}{3} }{ \frac{16^{2}}{4} \times 2 }

$\frac{23}{5}$
- $\frac{23}{5}$
- $\frac{1}{8}$
$\frac{21}{7}$

Solution:

$\frac{ \frac{27^{1}}{3} - \frac{8^{2}}{3} }{ \frac{16^{2}}{4} \times 2 }$

\frac{ \frac{27^{1}}{3} - \frac{8^{2}}{3} }{ \frac{16^{2}}{4} \times 2 }

=

\frac{3\sqrt{27} - 3\sqrt{8}^2}{\sqrt{16} \times 2}

\frac{3 - 4}{4 \times 2}

=

\frac{-1}{8}
