A = 6 - 5 * ( - 2 ) ³
A = 6 - 5 * ( - 8 )
A = 6 + 40 = 46
B = - 3 ⁴ * 0.1 - 4 ² * ( 3 - 1.01 )
B = - 81 * 0.1 - 16 * 1.99
B = - 8.1 - 31.84 = - 39.94
C = ( 25 + 15) ³ - ( 25 - 15 ) ³
C = 40 ³ - ( 10 )³
C = 64 000 - 100 = 63 900
D = ( 3/5) ² - 2 x 2 /5²
D = 9/25 - 2 x 2/25
D = 9/25 - 4 /25 = 5 /25 = 1 /5
