It's the only one that is fragrant, and the only one that blooms at night. Another authoritative source identified Hibiscus Moy Grande, a Hibiscus grandiflorus hybrid, as fragrant. Another cut flower advantage of Moy Grande is one of its parents, H. grandiflorus, is fragrant giving Moy Grande fragrance as well.
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 Ã 103 = 4000 . So 4000 can be written as 4 Ã 10Â³ . This idea can be used to write even larger numbers down easily in standard form. Small numbers can also be written in standard form. However, instead of the index being positive (in the above example, the index was 3), it will be negative. The rules when writing a number in standard form is that first you write down a number between 1 and 10, then you write Ã 10(to the power of a number). This video explains standard form: Example
The usual or standard state or manner of something. This word has a somewhat more technical meaning in mathematics. Two formulas such as 9 + x and x + 9 are said to be equivalent because they mean the same thing, but the second one is in canonical form because it is written in the usual way, with the highest power of x first.
