3! + 2x – yx
y = 5!!
x = -3
Percuma 🙂
Penjelasan dengan langkah-langkah:
y = 5!! = 5.3.1 =
15= 3! + 2x – yx
= (3.2.1) + 2(-3) – 15(-3)
= 6 + (-6) – (-45)
= 6 + (-6) + 45
= 0 + 45
= 45
Diketahui :
3! + 2x – yx = ?
Ditanya :
y = 5!!
x = -3
Jawab :
→ y
= 5!!
= 5 × 3 × 1
= 15 × 1
= 15
3! + 2x – yx
= 3! + 2(-3) – 15(-3)
= ( 3 × 2 × 1 ) + 2(-3) – 15(-3)
= ( 6 × 1 ) + 2(-3) – 15(-3)
= 6 + 2(-3) – 15(-3)
= 6 + -( 2 × 3 ) – 15(-3)
= 6 + (-6) – 15(-3)
= 6 + (-6) – -( 15 × 3 )
= 6 + (-6) – (-45)
= ( 6 – 6 ) – (-45)
= 0 – (-45)
= 0 + 45
= 45
- Kesimpulan :
→ Jadi, hasil nya adalah 45
