NISA [10]

Option C

<u>ANSWER: </u>

The scientific notation of 108200000 is $1.082 \times 10^{8}$ So the correct option is c.

<u>SOLUTION: </u>

Given,the average distance from Venus to the Sun is 108,200,000 kilometers.

We need to find the above given distance in the scientific notation.

Scientific notation is nothing but writing the large numbers as product of ten power something so that we can reduce space required to write that number.

Now, 108200000 can be written in scientific notation as:

= 10820000 x 10

$=1082000 \times 10^{2}$
