Question

4. What will be the sign of the product if we multiply the following?
a. 105 negative integers and 3 positive integers.
b. 64 negative integers and 1 positive integer.​

Answer 1

Answer:

a) -ve

b) +ve

explanation for both:

(-1×-1×-1×-1....n times = -1 where n is odd no.

= 1 where n is even no.

now, 1×1×1×1......n times = 1

where n= all even or odd no.)
