Question

( 1 supra 2 ) la a 2 • 6 - 1

Answer 1

1/2 ^2 = 1/4 * 6/1 = 1/2 * 3/1 = 3/2
3/2 - 1/1 = 3/2 - 2/2 = 1/2

Answer 2

${( \frac{1}{2} )}^{2} \times 6 - 1$

$= \frac{ {1}^{2} }{ {2}^{2} } \times 6 - 1$

$= \frac{1}{4} \times 6 - 1$

$= \frac{1 \times 6}{4} - 1$

$= \frac{6}{4} - 1$

$= \frac{3}{2} - 1$

$= \frac{3}{2} - \frac{2}{2}$

$= \frac{3 - 2}{2}$

$= \frac{1}{2}$
