Answer 2

Answer:

12615

Step-by-step explanation:

Given,

Product = 87*145

Apply distributive method,

87*(100+45)

= 87*100 +87*45

= 8700+3915

= 12615.

or this method can be apply in other as the difference of one number

= (100-13)*(145)

= 145*100 - 145*13

= 14500- 1885

= 12615

The product will remain same irrespective of the method chosen

Hence, the answer of the given question is 12615
