===========
9 : 9 + 9 × 9 - 9 + 2(9) - 9(1) +√9
1 + 9 × 9 - 9 + 18 - 9 + √3²
1 + 81 - 9 + 18 - 9 + 3
82 - 9 + 18 - 9 + 3
73 + 18 - 9 + 3
91 - 9 + 3
82 + 3
85

Penjelasan dengan langkah-langkah:
= x ÷ x + x × x - x + 2(x) - x(1) + √x
= 9 ÷ 9 + 9 × 9 - 9 + 2(9) - 9(1) + √9
= 1 + 81 - 9 + 18 - 9 + √3²
= 82 - 9 + 18 - 9 + 3
= 73 + 9 + 3
= 82 + 3
= 85
