Question

Daniela claims that multiplying by a power of 10 means adding zeros to the end of the number, with the number of zeros added equal to the power of 10. For instance, 6 × 102 can be evaluated by writing two zeros after 6 to get 600. Only some cases follow Daniela's claim. Select the expressions that follow Daniela's claim.

Answer 1

Daniel's claim is correct.

Explanation:

Claim: Daniela claims that multiplying by a power of 10 means adding zeros to the end of the number, with the number of zeros added equal to the power of 10.

Examples:

`6* 10^(2)=6* 100=600\ \ ;\text{2 0s added}\\\\6* 10^(3)=6* 1000=6000\ \ ;\text{3 0s added}\\\\6* 10^(4)=6* 10000=60000\ \ ;\text{4 0s added}`

Thus, Daniel's claim is correct.
