Answer 1

Given

Using the distributive law find " 521 ×162 "

Solution

So ,

→ 162 × ( 500 + 21 )

→ 162 × 500 + 162 × 21

→ 81000 + 3402

→ 84402 Ans !!

★ Know more about the properties

Closure property :

when a + b are rational numbers , the outcome

" a + b = c " is also a rational number !!

• As like , 2 + 6 = 8 , also a rational number

Commutative property :

The property in which , the rational numbers a + b is equals to b + a is called commutative property !!

• 5 + 6 = 6 + 5 = 11 , the value doesn't change

Associative law :

The law in which , the rational numbers a + ( b + c ) is equals to ( a + b ) + c !!

• 5 + ( 6 + 7 ) = ( 5 + 6 ) + 7 = 18 , the value remains unchanged

Distributive property :

a × ( b + c ) = ab + ac ... so this was distributive property !!

• 5 × ( 2 + 3 ) = 5 × 2 + 5 × 3
• 10 + 15 = 25 , " distributive property "
