greater instead of great
2/9 of 5/8 of 3/25 of ? = 40
√10000 x √8100 - (50)² = √(?) + (80)²
If x²y² + (1/ (x2y2)) = 83, then the value of xy – 1/xy is:
55% of ? = 45 + 20 × 6
(?) x 3 + 68 = √9025
(6630 ÷ 13 + 6120 ÷ 12) ÷ (17 × 3) = ?
(5/8) × 480 + (3/9) × 450 = (5/2) × ?
∛157464 =?
?2 = √20.25 × 10 + √16 + 32
I. 8x² - 74x + 165 = 0
II. 15y² - 38y + 24 = 0
