Answer:
[tex]10^{3}[/tex]
Step-by-step explanation:
Any positive integer power of 10 is the number of times 10 multiply by itself. In case power remain zero then the result will be just one.
[tex]10^{0} = 1\\ \\10^{1} = 10\\ \\10^{2} = 10\times 10 = 100\\ \\10^{3} = 10 \times 10\times 10 = 1000[/tex]
As given, we need to write 1000 as a power of 10
∴ [tex]10^{3} = 10\times 10\times 10 = 1000[/tex]
