Question

Find the product using suitable property (-62) x (91) + (91) (-38)​

Answer 1

The three consecutive whole numbers just preceding 7510001 are as follows:

7510001 − 1 = 7510000

7510000 − 1 = 7509999

7509999 − 1 = 7509998

∴ The three consecutive numbers just preceding 7510001 are 7510000, 7509999 and 7509998.

Answer 2

Answer:

Answer

To find the product using suitable properties  

(−57)×(−19)+57

As   we  know   that    

(−)×(−)=+

Therefore, we have  

(57)×(19)+57

=1083+57

=1140
