Let one focus of the hyperbola $ \frac{x^2}{a^2} - \frac{y^2}{b^2} = 1 $ be at $ (\sqrt{10}, 0) $, and the corresponding directrix be $ x = \frac{\sqrt{10}}{2} $. If $ e $ and $ l $ are the eccentricity and the latus rectum respectively, then $ 9(e^2 + l) $ is equal to:
The largest $ n \in \mathbb{N} $ such that $ 3^n $ divides 50! is:
Nomenclature of Organic Compounds can be defined as the systematic approach to name different organic compounds present in the world. In order to avoid some long and tedious common names in the general communication, the officials of the International Union of Pure and Applied Chemistry (IUPAC) have formulated some structured way of naming the organic compounds.
International Union of Pure and Applied Chemistry (IUPAC) introduced the classical nomenclature for the organic compounds systematically. Some rules were introduced such that every molecule has an individual name for its different structures.
Primary prefix + word root + primary suffix + secondary suffix
