Q.
[4/4]

100² × 4! + 20 - 30² = ... ?​

100² × 4! + 20 - 30² = ... ?

Penyelesaian

= 100² × 4! + 20 - 30²

= (100 × 100) × (4 × 3 × 2 × 1) + 20 - (30 × 30)

= 10.000 × (12 × 2 × 1) + 20 - 900

= 10.000 × (24 × 1) + 20 - 900

= 10.000 × 24 + 20 - 900

= 240.000 + 20 - 900

= 240.020 - 900

= 239.120

Jawaban:

239.120

Penjelasan dengan langkah-langkah:

[tex] {100}^{2} \times 4! + 20 - {30}^{2} [/tex]

[tex](100 \times 100) \times (4 \times 3 \times 2 \times 1) + 20 - (30 \times 30)[/tex]

[tex] = (10.000 \times 24) + 20 - 900[/tex]

[tex] = 240.000 + 20 - 900[/tex]

[tex] = 240.020 - 900[/tex]

[tex] = 239.120[/tex]
