:D 3! + 2x - yx y = 5!! x = -3 Percuma :)

😀
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 = ?

$\text{[math]}$

Ditanya :

y = 5!!

x = -3

$\text{[math]}$

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

→ Jadi, hasil nya adalah 45
