Question
The ratio of organic carbon to organic matter in soil
isSolution
Bemmelen factor is known in soil science as a conversion factor of 1.724 for estimating soil organic matter (OM) from soil organic carbon content (OC).
17.6% of 250 + √? = 70% of 90
30 of 20 - 40 + 182 - 23 × ? = 83Â
What will come in the place of question mark (?) in the given expression?
(286 ÷ 13 + 83) ÷ 15 × 8 + 84 = 400% of ?
464 + 181 +? = (154 × 25) - (15) 2 Â
Solve: 3/4÷2/3 ​
`(256/6561)(1/4) = ?`
Simplify the given expression:
[(2.3)3 + (15.9) ³ + (3.7) ³ – 3 × 2.3 × 15.9 x 3.7)] / [(2.3) ² + (15.9) ² + (3.7) ² – 2.3 ...
What will come in the place of question mark (?) in the given expression?
(√? - 17) X 40 + 145 = 1000 - 15Â
If x²- 5x + 1 = 0, what is the value of x² + 1/x2?
?2 × 25 = 42 × 21 + 172Â
