Question

solve using the distributive
properties for 420 X 139
find the product using suitable property ​

Answer 1

Answer:

Step-by-step explanation:

1 ) 420 × 139 = 420 × ( 130+9 )

a × ( b + c ) = a×b × a×c

420 × ( 130+9 ) = 420×130 + 420×9

= 54600 + 3,780

= 58,380

2 )

Answer 2

Concept

Distributive property

According to the distributive property, an expression of the form A (B + C) may be solved as A (B + C) = AB + AC. This distributive property applies to subtraction as well, and is written as A (B - C) = AB - AC. This indicates that operand A is shared by the other two operands.

Given

The expression 420 X 139.

To Find

We have to the product by using the suitable property.

Solution

Given 420 X 139.

Rewrite the expression.

420 X (130+9)

Apply distributive property

420×130+420×9= 54600+3,780

                           = 58,380

Hence the final answer is 58,380.
