The answer in decimal format is 1/900. Look at the question "i fun fact". Tell everyone else to look at "i fun fact" as well.

I agree with the first answer: 0.03. The problem statement is ambiguous. It's either:

(three times 10) to the negative 2 power

or

three times (10 to the negative 2 power)

In the absence of parentheses, the default order of operations is exponentiation first, followed by multiplication, so 10 is raised to the -2 power, and then multiplied by 3.

$${\mathtt{3}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{2}}} = {\mathtt{0.03}}$$ .
