Answer 2

Answer:

ans is option A

Step-by-step explanation:

scientific notation is one of the oldest mathematical short hand way to write very big and very

small numbers. This notation is also called standard form or exponential form of a number. The

scientific notation for any real number x has the form

n

m . rrrr 10 ± 321 L × (1.3)

where 9 1 ≤≤ ≤ 32 L,,,0,91 rrrr m ≤ and . n∈Z

The number m Lrrr 32 . is called the mantissa for x.

For example the real numbers,

51 ×10096.2 and 67 102906.1 − ×

are in scientific notation. In the first case

= = = 4321 = nrrrr = 51,6,9,0,2

and in the second case

= = = = 54321 = nrrrrr = − .6
