​

Answer 1

this question doesn't make any sense it is much harder and time consuming

Answer 2

Answer:

the value of (-1 )¹ +(-1 )² +(-1 )³+ (-1 )⁴....... +(-1 )¹⁰⁰ is 0

b'coz from 1 to 100 there are 50 odd no. and 50 even no.

we know that -1 raise to the power odd no. is -1

and -1 raise to the power even no. is 1.

So, (-1*50)+(1*50) =-50+50=00000
