2 soal sj :v ​

No. 1

= 5!! - (2! + 4! - 1)

= (5.3.1) - (2 + (4.3.2.1) - 1)

= 15 - (2 + (12.2) - 1)

= 15 - (2 + 24 - 1)

= 15 - (26 - 1)

= 15 - 25

= -10

• Hasilnya adalah Negatif 10.

__________________________________________

No. 2

Untuk nomor 2, gunakan sifat eksponen.

= 30¹² × 30² ÷ 30⁸

= 30(¹²+²-⁸)

= 30[tex]^{(14-8)}[/tex]

= 30[tex]^{6}[/tex]

• Hasil sederhananya adalah 30[tex]^{6}[/tex].

☁️Pertanyaan:

1.) 5!! - ( 2! + 4! - 1 ) = ?

[tex] \: [/tex]

2.) 30¹² × 30² ÷ 30⁸ = ?

☁️Jawaban:

1.) 5!! - ( 2! + 4! - 1 ) = [tex] \: -10 [/tex]

[tex] \: [/tex]

2.) 30¹² × 30² ÷ 30⁸ = [tex] \: {30}^{6}[/tex]

☁️Penyelesaian:

1.) 5!! - ( 2! + 4! - 1 )

• (5 × 3 × 1) - ((2 × 1) + (4 × 3 × 2 × 1) - 1)
• (15 × 1) - (2 + (12 × 2 × 1) - 1)
• 15 - (2 + (24 × 1) - 1)
• 15 - (2 + 24 - 1)
• 15 - (26 - 1)
• 15 - 25
• - 10✔️
