Question

Verify :
(ii) $(-82)\times \left[\right(-4)+19]=(-82)\times (-4)+(-82)\times 19$

Answer 1

Consider , L.H.S. $(-82)\times \left[\right(-4)+19]$

$=(-82)\times \left[\right(-4)+19]$
$=(-82)\times 15$
$=-1230$

Now, Consider R.H.S. $(-82)\times (-4)+(-82)\times 19$
$=(-82)\times (-4)+(-82)\times 19)$
$=328+(-1558)$
$=328-1558$
$=-1230$

$\therefore$ L.H.S = R.H.S = $-1230$

Hence. verified.
