2,000,000+700,000+80,000+1,000+9 in standard form?

1 answer

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:

\[ \boxed{2.781009 \times 10^6} \]
