(e) (-700)×49+(-700)​

Answer 1

Answer:

a)16 * 20 * - 25

=16*(20*-25)

=16*(-500)

=-8000

b)-125*17*-8

=(-125*-8)*17

=1000*17

=17000

c)-50× -14×12

=(-50*-14)*12

=700*12

=8400

d) (-25)× 36×80

=(-25*36)*80

=-900*80

=-72000

e)(-700)×49+(-700)​

=-700*(49+1)

=-700*50

=-35000

Answer 2

Answer:

(a) -8000

(b) 17000

(c) 8400

(d) -72000

(e) -35000

Step-by-step explanation:

(a) 16×20 ×(- 25)

= 16×{20×(-25)}

= 16×(-500)

= -8000

(b) (-125)×17×(-8)

= {-125(-8)}×17

= 1000×17

= 17000

(c) -50×(-14)×12

= {-50×(-14)}×12

=700×12

= 8400

(d) (-25)× 36×80

= (-25×36)×80

= (-900)×80

= -72000

(e) (-700)×49+(-700)​

= (-700)×(49+1)

= (-700)×50

= -35000
