Answer 1

1. 1) 26\times (-48)+(-48) \times (-36)=-48026×(−48)+(−48)×(−36)=−480

2) 625\times (-35)+(-625) \times (65)=-62500625×(−35)+(−625)×(65)=−62500

Step-by-step explanation:

To find : The product using suitable property ?

Solution :

1) 26\times (-48)+(-48) \times (-36)26×(−48)+(−48)×(−36)

Applying distributive property,

ab+ac=a(b+c)ab+ac=a(b+c)

Here, a=-48 , b=26 and c=-36

26\times (-48)+(-48) \times (-36)=-48(26+(-36))26×(−48)+(−48)×(−36)=−48(26+(−36))

26\times (-48)+(-48) \times (-36)=-48(26-36)26×(−48)+(−48)×(−36)=−48(26−36)

26\times (-48)+(-48) \times (-36)=-48(-10)26×(−48)+(−48)×(−36)=−48(−10)

26\times (-48)+(-48) \times (-36)=-48026×(−48)+(−48)×(−36)=−480

2) 625\times (-35)+(-625) \times (65)625×(−35)+(−625)×(65)

Applying distributive property,

ab+ac=a(b+c)ab+ac=a(b+c)

Here, a=625 , b=-35 and c=65

625\times (-35)+(-625) \times (65)=625(-35+(-1) \times (65))625×(−35)+(−625)×(65)=625(−35+(−1)×(65))

625\times (-35)+(-625) \times (65)=625(-35-65)625×(−35)+(−625)×(65)=625(−35−65)

625\times (-35)+(-625) \times (65)=625(-100)625×(−35)+(−625)×(65)=625(−100)

625\times (-35)+(-625) \times (65)=-62500625×(−35)+(−625)×(65)=−62500
