Step-by-step explanation:

(-1)^71 = -1

multiplying -1 by itself any odd number of times always gives -1.

multiplying -1 by itself any even number of times always gives 1.

2^2 + (-5)^3

= (2x2) + (-5 x-5 x-5)

= 5 + (-225)

= 220

2^8 / 2^6 = 2^2 = 4

(5^2) - (2^5)

= (5x5)-(2x2x2x2x2)

= 25 - 32

= -7
