QUIZ #125
Materi: Operasi Hitung

Jika diketahui :
a = 2
b = 4
c = 3
d = 9
Tentukan hasil dari 9a² - 5b + 8c × 5d !​​​​​​​​​​​​​​​​​

Answer 1

Diketahui :

a = 2

b = 4

c = 3

d = 9

Ditanya :

Hasil dari 9a² - 5b + 8c × 5d ?

Penyelesaian :

→ 9a² - 5b + 8c × 5d

→ 9a² - 5b + 40cd

→ 9(2²) - 5(4) + 40(3)(9)

→ 9(4) - 20 + 1.080

→ 36 - 20 + 1.080

→ 16 + 1.080

→ 1.096

Answer 2

Jawaban:

9a² = 9(2)² = 9(4) = 36

5b = 5(4) = 20

8c = 8(3) = 24

5d = 5(9) = 45

9a² - 5b + 8c × 5d

36 - 20 + (24(45))

16 + 1080

1.096
