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 the number, we look at the place value of the digit to the right of the one we want to round. In this case, the digit to the right is 0. Since 0 is less than 5, we round down. So, rounding 7,803,100 to the nearest place value gives us 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 × 10^6
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.
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 less than 5, we round down and the number becomes 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 × 10^6
To express the number of tourists visiting Country A, 7,803,100, in the form of a single digit times an integer power of 10, we can round it to the nearest place value.
Rounding 7,803,100 to the nearest place value gives us 7,800,000.
To express 7,800,000 in the form of a single digit times an integer power of 10, we can use scientific notation.
In scientific notation, we write a number as a decimal between 1 and 10, multiplied by a power of 10.
To express 7,800,000 in scientific notation, we can write it as 7.8 x 10^6.
So, the number of tourists visiting Country A can be expressed as 7.8 x 10^6.
To express a number in the form of a single digit times an integer power of 10, we need to find the appropriate power of 10.
In this case, the number of tourists visited is 7,803,100. To round this number to the nearest place value, we look at the digit to the right of the desired place value, which is the millions place.
The digit to the right of the millions place is 1, so we round down to 7,800,000 (since it is less than 5).
Now, we need to express this number in scientific notation. In scientific notation, we write a number as a single digit (between 1 and 9.9999) multiplied by a power of 10.
To determine the power of 10, we count the number of digits we moved to the left from the original number. In this case, we moved 6 digits to the left to get from 7,803,100 to 7,800,000.
Therefore, the number of tourists visited, 7,803,100, can be expressed as 7.8 × 10^6 (rounded to the nearest place value and expressed in scientific notation).
