Scientific notation has two parts: a number (say \(a\)) between one and ten, and that number multiplied by ten raised to the power \(b,\) where \(b\) is a non-zero integer: e.g. \( a \times 10^{b}, \) where \(1 \le a<10 \).
Find the value of \(a\) when you simplify the following expression in scientific notation to two decimal points:
\[(4.7 \times 10^{-3}) \times (6.1 \times 10^{9}). \]
