Question
What is the basis of the electrical conductivity method
for measuring soil moisture content?Solution
The electrical conductivity method is based on changes in electrical conductivity with changes in soil moisture. Gypsum blocks with two electrodes are used, and the conductivity across the electrodes is measured.
( 14.99%  of 549.99 ) × 17.02 = ? 2 + 26.02 × 3200 ÷ 800
Find the approximate value of Question mark(?). There is no requirement to find the exact value.
(2999.77 ÷ 74.85) + (√624.95 × 4.09) = ?
...`sqrt(224.991)` + (3.81008)2 = ? `-:` `1/6.0001`

66.05 × 17.95 – 38.99 × 18.12 = (60 + ?) × 6
Find the approximate value of Question mark(?). No need to find the exact value.
(34.95 × 7.03) ÷ 5 + 27.98% of 249.88 – √(80.81) = ?
...- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
