Question

Venus is the planet that comes nearest to Earth. It's closest position is about 38.000,000 kilometers from Earth. Write this number expressed as a product of 38 and a power of 10. I am in 5th grade and this is for math.

Answer 1

The distance as product of 38 and a power of 10 is
`38*10^(6)`

Explanation:

In math when we're dealing with big numbers like this we express them in power of 10, since it'll be easyer to read that way. We take the parts of the number to the left that are not equal to "0", in this case 38, and multiply it by a power of 10. The expoent to this power of 10 will be the number of "0" after the 38 and before the ",". In this case the closest distance from Earth to Venus is 38,000,000 (there's a typo in the question). So we take the 38 and multiply it by
`10^(6)`, since there are 6 zeros.

The distance as product of 38 and a power of 10 is
`38*10^(6)`
