প্রদত্ত রাশি,
$tan45^\circ \cdot sin^260^\circ \cdot tan30^\circ \cdot tan60^\circ$

$=1 \cdot \left(\frac{\sqrt3}{2}\right)^2 \cdot \frac{1}{\sqrt3} \cdot \sqrt3$

$=1 \cdot \frac{3}{4} \cdot \frac{1}{\sqrt3} \cdot \sqrt3$

$=1\cdot\frac34\cdot\frac1{\cancel{\sqrt3}}\cdot\cancel{\sqrt3}$

$=\frac{3}{4}$

$\therefore$ নির্ণেয় মান $\frac{3}{4}$
