Step-by-step explanation:

if you multiply negative 1(-1) with itself 100 times,it would be (-1)^100

if -1 is raised to the power of a number which is even,it will change its sign ie it becomes 1

whereas when it is multiplied by itself odd number of times like in (-1)^95,it would stay same ie -1

a=1

b=-1

so a + b = 1+(-1)=1-1=0
