Verified answer

A) -7² + (-7)² - 49 = 49 ==> 0

b) -2³-30+1 = - 8 - 30 + 1 ==> - 37

c) (- )³+1 = - 8 + 1 ==> - 8 + 27 ==> 19
27 27 27

d) -5²+(-3)²-10 = - 25 + 9 - 10 ==> - 26

e) 3³+   = 27 + 1 ==> 243 + 1 ==> 244
9 9   9

f)  -(-1).()² = 1 + 1.( 1 ) ==> 1 + 1 ==> 4+1 ==> 5
4 4 4 4
g) (1- = ( - 2+1 )^4 ==> ( - 3 )^4 ==>   81
2 4 256
