Answer 1

Răspuns:

Explicație pas cu pas:

0,6^2 = 0,36

1,95 : 1/2 = 1,95 x 2 = 3,9

0,36 + (8,1 - 3,9)x3,2: 21 = 0,36 + 4,2x3,2:21 = 0,36 + 13,44:21 = 0,36 + 0,64 = 1

Answer 2

( 0, 6 ) ^ 2 + ( 8, 1 - 1, 95 : 1 / 2 ) × 3, 2 : 21 =

0, 36 + ( 8, 1 - 1, 95 : 0, 5 ) × 3, 2 : 21 =

0, 36 + ( 8, 1 - 3, 9 ) × 3, 2 : 21 =

0, 36 + 4, 2 × 3, 2 : 21 =

0, 36 + 13, 44 : 21 =

0, 36 + 0, 64 = 1
