To express the sum \( 1,000,000 + 200,000 + 70,000 + 8,000 + 400 + 60 + 1 \) in standard form, we first add the numbers together:
- \( 1,000,000 \)
- \( 200,000 \)
- \( 70,000 \)
- \( 8,000 \)
- \( 400 \)
- \( 60 \)
- \( 1 \)
Now, let's calculate the total:
\[ 1,000,000 + 200,000 = 1,200,000 \] \[ 1,200,000 + 70,000 = 1,270,000 \] \[ 1,270,000 + 8,000 = 1,278,000 \] \[ 1,278,000 + 400 = 1,278,400 \] \[ 1,278,400 + 60 = 1,278,460 \] \[ 1,278,460 + 1 = 1,278,461 \]
The total sum is \( 1,278,461 \).
Now, to express \( 1,278,461 \) in standard form (also known as scientific notation), we want to write it in the form of \( a \times 10^n \), where \( 1 \leq a < 10 \) and \( n \) is an integer.
In this case, we can express it as follows:
\[ 1,278,461 = 1.278461 \times 10^6 \]
Thus, the number \( 1,278,461 \) in standard form is:
\[ 1.278461 \times 10^6 \]
