Answer 1

Jawaban:

Diketahui :

• f(x) = x ÷ x × x + x - x × x + x

-----

Ditanya :

• f(9) = ...?

---

Dijawab :

• f(x) = x ÷ x × x + x - x × x + x
• f(9) = 9 ÷ 9 × 9 + 9 - 9 × 9 + 9
• f(9) = ( 9 ÷ 9 ) × 9 + 9 - 9 × 9 + 9
• f(9) = ( 1 × 9 ) + 9 - 9 × 9 + 9
• f(9) = 9 + 9 - 9 × 9 + 9
• f(9) = 9 + 9 - ( 9 × 9 ) + 9
• f(9) = 9 + 9 - 81 + 9
• f(9) = 18 - 81 + 9
• f(9) = (-63) + 9
• f(9) =

-------

Kesimpulan :

• maka, nilai dari f(9) adalah

Answer 2

Penjelasan dengan langkah-langkah:

☞ f(x) = x ÷ x × x + x - x × x + x

☞ f(9) = 9 ÷ 9 × 9 + 9 - 9 × 9 + 9

☞ f(9) = ( 9 ÷ 9 ) × 9 + 9 - 9 × 9 + 9

☞ f(9) = ( 1 × 9 ) + 9 - 9 × 9 + 9

☞ f(9) = 9 + 9 - 9 × 9 + 9

☞ f(9) = 9 + 9 - ( 9 × 9 ) + 9

☞ f(9) = 9 + 9 - 81 + 9

☞ f(9) = 18 - 81 + 9

☞ f(9) = (-63) + 9

☞ f(9) = -54
