a
-7² + (-7)² = -49 + ( +49) = -49 + 49 = 0***
b
-2³ - 30 + 1 = - 8 - 30 + 1 = - 37 ***
c
-(2/3)³ + 1/1 = - ( + 8/27) + 1/1 = - 8/27 + 1/1 = ( -8 + 27)/27 = 19/27 ***
d
-5² + ( -3)² - 10 =
-25 + (+9) - 10 = -25 + 9 -10 = - 26 ***
e
3² + 3⁻² = 9 + (1/3)² = 9/1 + 1/9 = ( 81 + 1)/9 = 82/9 ***
f
5⁰ - ( -1) - ( - 1/2)²
1 + 1 - ( + 1/4) =
2/1 - 1/4 = ( 8 - 1)/4 = 7/4***
