Question

find the products when -1 is multiplied to 2 m times where m is any natural number​

Answer 1

Answer:

The final product can only be 2 or -2

if you multiply 2 with (-1) m times when m is odd

the product will be -2.

for example :- 2 x -1 = -2

2 x -1 x -1 x -1 = -2.

SIMILARLY, if you multiply 2 with -1 m times when m is even

the product will be 2.

for example :- 2 x -1 x -1 = 2

2 x -1 x -1 x -1 x -1 = 2
