Answer 1

Use this trick: 
place the very 1st digit then put a point. Now, count the no. of digits ignoring the very 1st one u already placed.. In this case no. of digits ignoring 8 is eight. so write

Answer 2

Answer:

$8.01\times 10^8$

Step-by-step explanation:

Since, in the scientific notation we write a very large number or very small number as the product of a number between 0 to 9 and an exponent of 10,

Also, when we obtain a number between 0 to 9 by shifting decimal to left side then the power of 10 is positive number of shifting,

Now, we have a number,

801,000,000

Thus, by the above explanation,

the scientific notation of 801,000,000 is $8.01\times 10^8$
