Question

find the product by using the suitable properties

1: 15×4×(-10)×(-25)

2: 8×63×(-125)

3:(-5)×32×(-20)×4

4:(-16)×26+(-16)×-36
​

Answer 1

Step-by-step explanation:

15×4×(-10)×(-25)

60×250

1500

Answer 2

1. 15000

2. - 63000

3. 12800

4. 160

Step-by-step explanation:

1. 15 × 4 × (-10) × 25

=> 15 × (-10) × 25 × 4...[commutative property]

=> (-150) × 100

=> - 15000

2. 8 × 63 × (-125)

=> 63 × (-125) × 8....[commutative property]

=> 63 × (-1000)

=> - 63000

3. (-5) × 32 × (-20) × 4

=> 32 × 4 × (-20) × (-5)...[commutative property]

=> 128 × 100

=> 12800

4. (-16) × 26 + (-16) × (-36)

=> (-16) × {26 + (-36)}...[distributive property]

=> (-16) × (-10)

=> 160

Hope it helps.
