Characteristics of saline soils: · Soil pH of · ECis >4.0 millimhos/cm. · ESP is < 15% · Dominated by sulphate and chloride ions and low in exchangeable sodium.
If x = 107, then find the value of x(x2 - 12x + 48) ?
If x – 1/x = 9, then x3 – 1/x3 is:
If x = 15, find x5 - 16x4 + 16x3 - 16x2 + 16x - 16 = ?
if 3y-3/y=8 then find the value of y ² +1/y²
If 9x2 + 16y2 = 24xy, then find the ratio of ‘x’ and ‘y’, respectively.
If 0.125x3 +0.216y3 = 210 and 0.25x2 + 0.36y2 = 10.30 then find the value of 0.5x + 0.6y.
1/3 + 1/15 + 1/35 + 1/63 + 1/99 = ?
