Ethylene is a naturally occurring plant hormone that is also used artificially to speed up the ripening process of fruits. It triggers the production of enzymes that soften the fruit and convert starches into sugars.
If x - 1/x = 9, then the value of x² + 1/ x² is:
(33 + 6.25% of 4096) = ? + 2 × 119
3 √8 × √36 × 13 = ? × √169
{(123 + ? × 28) – 1254} × (2328 ÷ 97 – 13) = 8195
40 of 30% of 220 = ? + 790
5121.3 × 641.8 ÷ 80.5 = 8?
81% of 2300 – 34% of 550 = ?
√14400 x √8100 - (60)² = ? + (80)²
