$\frac{1}{2} \times 2^{(x-3)} + 1 = 5$
বা, $\frac{1}{2} \times 2^{(x-3)} = 5-1$
বা, $\frac{1}{2} \times 2^{(x-3)} = 4$
বা, $2^{(x-3)} = 4 \times \frac{2}{1}$
বা, $2^{(x-3)} = 8$
বা, $2^{(x-3)} = 2^3$
বা, $x - 3 = 3$
বা, $x = 3 + 3$
$\therefore x = 6$
$\frac{1}{2} \times 2^{(x–3)}+1=5$ হলে $x$ এর মান $6$
