Question

(i) product of two different integers can be zero.
(ii) product of 120 negative integers and 121 positive integers is negative
(iii) ax (b + c) = a × b + c​

Answer 1

(i) False.

(ii) False.

Correct : Since 120 integers are even in numbers, hence the product will be positive and for 121 positive integers the product will be positive. Therefore the product of 120 negative integers and 121 positive integers will be positive.

(iii) False.

Correct: a\times\left(b+c\right)\ne a\times b+ca×(b+c)



=a×b+c

= ab+bc\ne ab+cab+bc



=ab+c
