b = 80 - 50 + 30 - 1!
c = 90 + 2 × 2!
Tentukan :
1.) a + b × c + c - b - a
2.) a ÷ a × b + c × a + c​

Answer 1

a = 90 + 30 - 100 = 120 - 100 = 20b = 80 - 50 + 30 - 1! = 30 + 30 - 1! = 60 - (1 × 1) = 60 - 1 = 59c = 90 + 2 × 2! = 90 + 2 × (1 × 2) = 90 + 2 × 2 = 90 + 4 = 94 a = a + b × c + c - b - a = 20 + 59 × 94 + 94 - 59 - 20 = 20 + 5.546 + 94 - 59 - 20 = 5.566 + 94 - 59 - 20 = 5.660 - 59 - 20 = 5.581 ✔️b = a ÷ a × b + c × a + c = 20 ÷ 20 × 59 + 94 × 20 + 94 = 1 × 59 + 94 × 20 + 94 = 59 + 1.880 + 94 = 1.939 + 94 = 2.033 ✔️Teu - ba ~
