Explicație pas cu pas:
a) a = ( 1 + 2 la puterea 3 ) × 2 la puterea 60
a = ( 1 + 8 ) × 2 la puterea 60
a = 9 × 2 la puterea 60
b) b = ( 3 la puterea 2 - 5 ) × 3 la puterea 20
b = ( 9 - 5 ) × 3 la puterea 20
b = 4 × 3 la puterea 20
c) c = ( 2 la puterea 4 + 9 ) × 2 la puterea 20
c = ( 16 + 9 ) × 2 la puterea 20
c= 25 × 2 la puterea 20
d) d = ( 3 + 3 la puterea 3 + 19 ) × 3 la puterea 12
d = ( 3 + 27 + 19 ) × 3 la puterea 12
d = 49 × 3 la puterea 12
