Write the number in decimal notation without the use of exponents.
\[
2.47 \times 10^{-2}
\]
\[
2.47 \times 10^{-2}=
\]

Step 1 ：The problem is asking to convert a number from scientific notation to decimal notation. In scientific notation, the number is written as a product of two factors: a number between 1 and 10 (in this case, 2.47) and a power of 10 (in this case, \(10^{-2}\)). To convert this to decimal notation, we need to move the decimal point of the first factor two places to the left (because the exponent of 10 is -2).

Step 2 ：The Python code correctly converted the number from scientific notation to decimal notation. However, due to the limitations of floating point precision, the result is not exactly 0.0247, but very close to it. We can round the result to four decimal places to get the exact decimal notation.

Step 3 ：Final Answer: \(2.47 \times 10^{-2} = \boxed{0.0247}\)
