Q:

The expression of 5008 km in scientific notation is

A) 50.08 x 10^3 kms B) 5.008 x 10^-3 kms
C) 5.008 x 10^3 kms D) 500.8 x 10^3 kms
 
Answer & Explanation Answer: C) 5.008 x 10^3 kms

Explanation:

We know that, any decimal number when multiplied by the multiples of 10, the decimal point moves to right the number of zeroes in the multiplying number.

 

For example :: 

0.0410 x 100 = 4.10 (Number of zeros in 100 are 2. So, the decimal point in 0.0410 moves two places to the right and becomes 4.10.)

 

Similarly, here in the option C) 5.008 x 10^3 kms it makes 5008 kms as the number of zeros in 10^3  i.e,  1000 are 3 and 5.008 becomes 5008.
