Question

if the productbof two whole numbers is 1 ,can we say that one or both of them will be 1 ? justify through examples.
​

Answer 1

Answer:

1. is the identity for multiplication of whole no or multiplicative indetity for whole number remain unchanged when multipled by hence the product of two whole no will be qual to one if and only if both whole number are 1

1×1=1

2×1=2

3×1=3

10×1=10

1000×1=1000 Thus, if the product is 1, both number should be 1

therefore 1×1=1 is the only possible equation
