ii)= positive
Step-by-step explanation:i) as we know product of any two negative numbers is positive but the product three negative numbers(we can also say odd number of negative numbers is negative) so product of 5 negative numbers is negative and product of 2 postive numbers is positive so finally the product of one negative and one positive is negative
ii) same for second question product of 4 negative numbers is positive and product of 7 positive numbers is positive and finally those two product is positive
