To express the sum of \(2,000,000 + 700,000 + 80,000 + 1,000 + 9\) in standard form, we first need to calculate the total.
Let's add these numbers together:
\[ 2,000,000 + 700,000 = 2,700,000 \]
\[ 2,700,000 + 80,000 = 2,780,000 \]
\[ 2,780,000 + 1,000 = 2,781,000 \]
\[ 2,781,000 + 9 = 2,781,009 \]
Now, we have the total as \(2,781,009\).
To express \(2,781,009\) in standard form (which is usually represented as \(a \times 10^n\), where \(1 \leq a < 10\)), we can rewrite the number as follows:
\[ 2,781,009 = 2.781009 \times 10^6 \]
Therefore, the standard form of \(2,000,000 + 700,000 + 80,000 + 1,000 + 9\) is:
\[ \boxed{2.781009 \times 10^6} \]
