sum of two even numbers is even
sum of two odd numbers is even
sum of one odd and one even is odd (49)
let's say a is odd and b is even
thus
(-1)^odd +(-1)^even = -1+1 =0
thus value of (-1)^a+(-1)^b = 0
que no. 2 ) A+√B = 0
thus √B = -A
square root of a real number can not be negative
thus A= 0
B = 0
