Question

Which product has 4 zeros after the digit 3? 0.03 times 10 with the power of 5. 0.3 times 10 with the power of 4 0.03 times 10 with the power of 4. 0.03 times 10 with the power of 5

Answer 1

`0.3 * 10^5`

Explanation:

0.3

^ You need to move the three before the decimal place and leave 4 empty digits (0) between

0.3

3.0

30.0

300.0

3000.0

30000.0

A total of 5 moves.

Each move is equivalent to x, the preceding value, times 10. x * 10

Repeated multiplication times the same factor equates to exponentiation, so for a total of 5 moves, it is notated as
`10^5`, giving you an expression of:

`0.3 * 10^5`
