Answer 2

Answer: 73528

Step-by-step explanation: There are four main types of properties of numbers – Commutative property, Associative property, Identity property and Distributive property.

According to the commutative property, the numbers on which we perform mathematical operations have the same result irrespective of the order of arrangement of terms, associative property is similar to the commutative property, when three or more than three terms are added (or multiplied) the result is the same irrespective of the grouping of numbers. Identity property is followed by a number which after undergoing a mathematical operation gives its own value as the answer.

We have to find 728×101 by the distributive property, so the statement can be rewritten as –

728×101=728(100+1)

Now, we multiply 728 individually with both the terms in the bracket that is 100 and 1

728(100+1)=728×100+728×1=72800+728

Adding the two obtained terms we get –

728×101=73528

Hence 73528 is the correct answer.

So, the correct answer is “ 73528 ”.
