2,000,000+500,000+10,000+1,000+700+80+7 in standard form?

1 answer

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:

\[ \boxed{2.511787 \times 10^6} \]
