Question 17

$(-25)\times [6+4]$ is not same as

(a) $(-25)\times 10$
(b) $(-25)\times 6+(-25)\times \left(4\right)$
(c) $(-25)\times \left(6\right)\times \left(4\right)$
(d) -250

Answer 1

$(-25)\times [6+4]=(-25)\times 10Also,(-25)\times [6+4]=-25\times 6+(-25)\times 4$ [using distributive property, i.e. $a\times (b+c)=a\times b+a\times c$]
= - 150 -100 = -250
Hence, $(-25)\times (6+4)$ is not same as $-25\times 6\times 4$
