Phosphatic fertilizers are produced from phosphate rock, which is a natural mineral resource. Phosphate rock deposits can contain trace amounts of various elements, including Uranium-238. During the extraction and processing of phosphate rock to produce phosphatic fertilizers, there is a possibility of unintentional contamination with Uranium-238.
√675 + √785 = ? × 8.995
(44.85% of 799.77 - √143.84)² ÷ (9/11 × 76.77) = ?
837.04 × 4.02 + 40.04% of 3049.98 – 3667.82 = ? 2 – 60.87
(51.99² - 19.05² )÷ ? = 14.11² - 140.33
? = 19.89% of (29.89 × 12.44) + 9.96 × 12.022
(8.013 – 20.04) = ? + 6.98% of 5399.98
(2520.33 ÷ 41.67) × (√168.88 + √80.78) - 10% of 1499.85 = ?
(?)2 + 4.113 = 24.92 – 32.03
102.89 of 3.08 = 59.98% of 499.94 + √?
