QUESTION: Dear Prof Azeem

http://en.wikipedia.org/wiki/Scientific_notation

http://en.wikipedia.org/wiki/Complex_number

A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, where i2 = −1.

Is it possible to also have a scientific notation for complex numbers ?.

Examples :

6720000000 + 4i

1991230000000 + 6i

18.7 + 2i

Awaiting your reply,

Thanks & Regards,

Prashant S Akerkar

ANSWER: Hi Prashant,

It is possible to use scientific notation for either the real or imaginary part or both. Scientific notation is just that: notation. It does not matter what it is representing. Any number can be represented in scientific notation, in theory.

Thanks for asking,

QUESTION: Dear Prof Azeem

1. Can this also be taken as a valid example and written with scientific notations ?.

Here a & b are large numbers

6720000000 + 1991230000000i

Similarly example of small numbers

0.0000000000345 + 0.34562222222222i

i.e. a+bi complex form where a,b are real numbers.

2. The mathematical computations viz Multiplication, Division of two complex numbers where a & b for very large or very small numbers with use of scientific notation (10^9 OR E9) can become complex ?.

3. Is it possible also to compute for exponentiation where base and exponent are complex numbers

for example :

http://en.wikipedia.org/wiki/Exponentiation

Base = 6720000000 + 1991230000000i

Exponent = 0.0000000000345 + 0.34562222222222i

Awaiting your reply,

Thanks & Regards,

Hi Prashant,

All the operations you mentioned can be performed using real or complex numbers written in scientific notation. The justification is the same as above: scientific notation is merely a different way of writing the same number.

Azeem
