After tillage operations the Bulk density of tilled soil as compared to untilled soil
The goals of tillage is to reduce bulk density (increasing soil porosity).
(64/25)? × (125/512)?-1 = 5/8
√(2670+ √(1141+ √(260- √(1251- √(637+ √1521) ) ) ) ) =?
1/6+ 999*53/54 ×9 = ?
1549.8 ÷ 8.2 + 65.6 × 55 = (? × 4) + (42 × 30.5)
(560 ÷ 32) × (720 ÷ 48) = ?
(18 x 3) + (36 x 8) = ? + 10
(5832) 2/3 / (104976)3/4X ? = (`sqrt(18)` ` ` ) 5
...175 + 24% of 450 = 350 + ?
`sqrt(7744)` - `sqrt(4761)` + `sqrt(8281)` + `sqrt(5625)` + ? = 1856
?% of 320 = 40% of 40 × 5
