Question

1 state state the sign of the product if a b c d e f g and h are positive integers.
a. (-a) ×(-b)×c×(-d)×(-e)×f×g×(-h) ​

Answer 1

Answer:

the sign of the product will negative

Step-by-step explanation:

a,b,c,d,e,f,g are all positive integers

so negative of positive integers are negative value

so -a=-a

-b=-b

-d=-d

-e=-e

-h=-h

AND WE KNOW (-)×(-)=(+)

(-)×(+)=(- )

(+)×(-)=(-)

(+)×(+)=(+)

so { (-)×(-)}×{(+)×(-)}×{(-)×(+)}×{(+)×(-)}

={(+)×(-)}×{(-)×(-)}

=(-)×(+)=(-)
