Question

4.500,0000 write in standard form

Answer 1

45000000/10 ans 4500000

Answer 2

Standard form

Standard form is a way of writing down very large or very small numbers easily. 10^3 = 1000, so 4 × 10^3 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Now answer for your question is :

 

NaN x 10^-9

NaN. In the IEEE 754-2008 standard (referred to as IEEE 754 henceforth), NaN (or "not a number") is a symbolic floating-point representation which is neither a signed infinity nor a finite number.

This means your question is incorrect !

Hope this may help you and be the brainliest ..
