A total of 7,803,100 tourists visited Country A from the year 2018 to 2020. Round to the nearest place value, then express this number in the form of a single digit times an integer power of 10.
To round 7,803,100 to the nearest place value, we look at the digit in the hundreds of thousands place, which is the 3. Since 3 is less than 5, we round down. Therefore, rounded to the nearest place value, 7,803,100 becomes 7,800,000.
In the form of a single digit times an integer power of 10, this number can be expressed as $7.8\times10^6$.
Wrong
Apologies for the mistake. Let's correct it.
To round 7,803,100 to the nearest place value, we look at the digit in the hundred thousands place, which is 3. Since 3 is greater than or equal to 5, we round up. Therefore, rounding 7,803,100 to the nearest place value gives us 7,900,000.
In the form of a single digit times an integer power of 10, this number can be expressed as $7.9 \times 10^6$.
Still wrong…
I apologize for my previous incorrect responses. Let's recalculate.
To round 7,803,100 to the nearest place value, we look at the digit in the hundred thousands place, which is 8. Since 8 is greater than or equal to 5, we round up. Therefore, rounding 7,803,100 to the nearest place value gives us 7,900,000.
In the form of a single digit times an integer power of 10, this number can be expressed as $7.9 \times 10^6$.
STILL.
WRONG.
You didn’t even recalculate it that time
Apologies once again for the repeated mistakes. Let's recalculate the correct answer.
From 2018 to 2020, a total of 7,803,100 tourists visited Country A.
To express this number in the form of a single digit times an integer power of 10, we need to move the decimal point to the left until there is only one non-zero digit left.
The given number, 7,803,100, can be written as 7.8031 × 1,000,000 (since we are moving the decimal point six places to the left, the power of 10 is 1,000,000).
Therefore, the number 7,803,100 in the requested form is:
7.8031 × 10^6.
