Answer:

प्रश्न 1.

निम्नलिखित गुणनफलों को ज्ञात कीजिए :

(a) 3 x (-1)

(b) (-1) x 225

(c) (-21) x (-30)

(d) (-316) x (-1)

(e) (-15) x 0 x (-18)

(f) (-12) x (-11) x 10

(g) 9 x (-3) x (-6)

(h) (-18) – (-5) (-4)

(i) (-1) (-2) (-3) x 4

(j) (-3)x (-6) (-2) x (-1)

हल:

(a) 3 x (-1) = – (3 x 1) = -3

(b) (-1) x 225 = – (1 x 225) = – 225

(c) (-21) x (-30) = + (21 x 30)

= [(20+ 1) x 30] = 20 x 30+ 1 x 30

= 600 + 30 = 630

(d)(-316) x (-1) = + (316 x 1)= 316

(e) (-15) x 0 x (- 18)

= [(- 15) x 0] x (-18)

= 0 x (-18) = 0

(f) (-12) x (-11) x 10

= + [(12 x 11) x 10]

= 132 x 10 = 1320 उत्तर

(∵ ऋणात्मक पूर्णांकों की सम संख्याओं का गुणनफल धनात्मक होता है)

(g) 9x (-3) x (-6) = + (9 x 3 x 6) = 162

(h) (-18) x (-5) x (-4) = -(18 x 5 x 4) = -360 (∵ ऋणात्मक पूर्णांकों की विषम संख्याओं का गुणनफल ऋणत्मक होता है)

(i) (-1)- (-2) x (-3) x 4 = – (1 x 2 x 3 x 4)= – 24

(j) (-3) x (-6) x (-2) (-1) = + (3 x 6 x 2 x 1) = 36

HOPE IT HELPS YOU ✌️✌️
