To convert the expression \(2,000,000 + 500,000 + 10,000 + 1,000 + 700 + 80 + 7\) into standard form, we first need to find the total sum.
Adding the numbers together:
\[ 2,000,000 + 500,000 = 2,500,000 \] \[ 2,500,000 + 10,000 = 2,510,000 \] \[ 2,510,000 + 1,000 = 2,511,000 \] \[ 2,511,000 + 700 = 2,511,700 \] \[ 2,511,700 + 80 = 2,511,780 \] \[ 2,511,780 + 7 = 2,511,787 \]
Now that we have the total, \(2,511,787\), we convert it to standard form.
Standard form (also known as scientific notation) is expressed in the form \(a \times 10^n\), where \(1 \leq a < 10\) and \(n\) is an integer.
For \(2,511,787\), we write it as:
\[ 2.511787 \times 10^6 \]
So the answer in standard form is:
\[ \boxed{2.511787 \times 10^6} \]
