Question 5

Q5) 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 5)

(a) 26 × (– 48) + (– 48) × (–36)

(– 48) [ 26 +(–36) ]

(– 48) × [-10]

= 480

(b) 8 × 53 × (–125)

53\times[8\times(-125)]53×[8×(−125)]

53\times\left(-1000\right)53×(−1000)

=\ -53000= −53000

(c) 15 × (–25) × (– 4) × (–10)

15\times\left(-1000\right)\ =-1500015×(−1000) =−15000

(d) (– 41) × 102

-41\times\left[100+2\right]−41×[100+2]

-41\ \times\ 100\ +\left[\left(-41\right)\times2\right]−41 × 100 +[(−41)×2]

-4100+\left(-82\right)\ \ =\ -4182−4100+(−82) = −4182
