A total of 7,803,100 tourists visited Country A from the year 2018 to the year 2020. Round to the nearest place value, then express this number in the form of a single digit times an integer power of 10.(1 point)
7,803,100 can be rounded to 7,800,000.
To express this number in the form of a single digit times an integer power of 10, we can write it as 7.8 x 10^6.
To express the number 7,803,100 in the form of a single digit times an integer power of 10, we need to round it to the nearest place value.
Rounding 7,803,100 to the nearest place value gives us 8,000,000.
Now, let's express 8,000,000 in scientific notation.
8,000,000 can be written as 8 × 10^6.
Therefore, the number of tourists visiting Country A, rounded to the nearest place value and expressed in the form of a single digit times an integer power of 10, is 8 × 10^6.
To express the number 7,803,100 in the form of a single digit times an integer power of 10, you need to identify the place value of the digit that will be the single digit.
The largest place value in 7,803,100 is the hundred thousands place, which is represented by the digit 7. To round to the nearest place value, you need to look at the digit to the right of the hundred thousands place, which is a 8 in this case.
If the digit to the right of the hundred thousands place is less than 5, you keep the digit as it is. However, if the digit is 5 or greater, you increase the digit in the hundred thousands place by 1. Since the digit to the right (8) is greater than 5, we increase the digit 7 by 1.
Therefore, the rounded number is 8,000,000. In scientific notation, this can be expressed as 8 x 10^6.
So, the answer is 8 x 10^6.
