To express the sum \(9,000,000 + 800,000 + 70,000 + 4,000 + 700 + 90 + 4\) in standard form, we first need to calculate the total:
\[ \begin{align*} 9,000,000 + 800,000 & = 9,800,000 \ 9,800,000 + 70,000 & = 9,870,000 \ 9,870,000 + 4,000 & = 9,874,000 \ 9,874,000 + 700 & = 9,874,700 \ 9,874,700 + 90 & = 9,874,790 \ 9,874,790 + 4 & = 9,874,794 \ \end{align*} \]
Now the total sum is \(9,874,794\).
Next, we convert \(9,874,794\) into standard form. Standard form expresses numbers as a product of a number between 1 and 10 and a power of 10.
To express \(9,874,794\) in standard form:
- Move the decimal point to create a number between 1 and 10: \[ 9.874794 \times 10^7 \]
Thus, the number \(9,874,794\) in standard form is:
\[ \mathbf{9.874794 \times 10^7} \]
