To calculate these expressions, follow the order of operations (PEMDAS):
(1,2^2 - 1,8^2)(1,2^2 = 1,441,8^2 = 3,241,44 - 3,24 = -1,8)
(1,2° \times 0,6 - 1,8° \times 0,96)(1,2° \times 0,6 = 0,721,8° \times 0,96 = 1,7280,72 - 1,728 = -1,008)
Therefore:
To calculate these expressions, follow the order of operations (PEMDAS):
(1,2^2 - 1,8^2)
(
1,2^2 = 1,44
1,8^2 = 3,24
1,44 - 3,24 = -1,8
)
(1,2° \times 0,6 - 1,8° \times 0,96)
(
1,2° \times 0,6 = 0,72
1,8° \times 0,96 = 1,728
0,72 - 1,728 = -1,008
)
Therefore:
(1,2^2 - 1,8^2) = -1,8(1,2° \times 0,6 - 1,8° \times 0,96) = -1,008
