Question

if a=(-1)multiple (-1)multiple(-1)...100times and b=(-1)multiple (-1)multiple(-1)multiple(-1) 95times then a+b=?​

Answer 1

Answer:

a= (-1) to the power 100 b= (-1) to the power 95 then a+b = (-1) to the power 100 + (-1) to the power 95 = 1 + (-1) ( as 100 is a even and 95 is a odd number) = 1-1= 0 . The answer is 0
