Find the product, using suitable properties:
(a) 26 × (– 48) + (– 48) × (–36)
(b) 8 × 53 × (–125)
(c) 15 × (–25) × (– 4) × (–10)
(d) (– 41) × 102
(e) 625 × (–35) + (– 625) × 65
(f) 7 × (50 – 2)
(g) (–17) × (–29)
(h) (–57) × (–19) + 57
Solution:
a) 26 × (-48) + (-48) × (-36)
Using distributive property, we get
(a × b) + (b × c) = b × (a + c)
= (-48) × [26 + (-36)]
= (-48) × [26 - 36]
= (-48) × (-10)
= 480
b) 8 × 53 × (-125)
Using associative property, we get
(a × b) × c = a × (b × c)
= 8 × (53 × -(125))
= 8 × -6625
= -53000
c) 15 × (-25) × ( -4) × (-10)
Using associative property, we get
= 15 × [(-25) × (-4) × (-10)]
= 15 × [(100) × (-10)]
= 15 × (-1000)
= -15000
d) (-41) × 102
Using distributive law, we get
= (-41) × (100 + 2)......[a × (b + c)] = (a × b + a × c)
= (-41) × 100 + (-41) × 2
= -4100 - 82
= -4182
