Question

331 × 129 - 331 × 29 usimg a suitable property
​

Answer 1

Answer:

Given -:

331 × 129 - 331 × 29 usimg a suitable property

To find -:

Find 331 × 129 - 331 × 29 using a suitable property.

Solution -:

• We can do that by using associative property.

Associative property -:

In mathematics, the associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.

According to the question, now we have to solve it by associative property -:

• = 331 × 129 - 331 × 29
• = 331 × ( 129 - 29 )
• = 331 × 100
• = 33,100

Hence,the answer is 33,100.
