Step 1 :The question is asking to convert a number from scientific notation to standard notation. In scientific notation, the format is a \(a \times 10^n\), where \(1 ≤ a < 10\) and \(n\) represents the number of places to move the decimal point. If \(n\) is positive, move the decimal point to the right. If \(n\) is negative, move the decimal point to the left. In this case, we have \(1.986 \times 10^{6}\), so we need to move the decimal point 6 places to the right.
Step 2 :The standard notation of \(1.986 \times 10^{6}\) is \(\boxed{1986000}\).
