Answer 2

Given :  product of the a)28 times of the negative integers b) 13 times of the negative integers ​

To find : sign of the product

Solution:

Negative integer  - x

can be written as (-1) * (x)   where x is + ve

i.e  (-1) ( magnitude of integer )

product of  28 times of the negative integers  

= (-1)²⁸ *  multiplication of  magnitude of integers

= ((-1)²)¹⁴ * multiplication of  magnitude of integers  

= (1)¹⁴ * multiplication of  magnitude of integers  

= (+ve)(+ve)

= + ve

28 times of the negative integers  is  + Ve

product of  13 times of the negative integers  

= (-1)¹³  *  multiplication of  magnitude of integers

= ((-1)²)⁶ * (-1)  * multiplication of  magnitude of integers  

= (1)⁶ * (-1)  * multiplication of  magnitude of integers  

= (+ve)(-1)(+ve)

= + ve (-1)

= - ve

13 times of the negative integers  is  - Ve
