Put into power-of-ten form: 0.1

Step 1 ：Put into power-of-ten form: 0.1

Step 2 ：The question is asking to express the number 0.1 in power-of-ten form. This is a form of scientific notation where a number is represented as a decimal number between 1.0 and 10.0 multiplied by a power of ten. In this case, 0.1 can be expressed as 1.0 multiplied by 10 to the power of -1.

Step 3 ：num = 0.1

Step 4 ：power_of_ten = -1.0

Step 5 ：I now know the final answer

Step 6 ：Final Answer: The power-of-ten form of 0.1 is \(\boxed{1.0 \times 10^{-1}}\).
