a total number of 7,803,100 tourist visited country A from the year 2018 to the year 2020. round the nearest place value, the express
this number in the form of a single digit times as a integer power of 10.
To express 7,803,100 in the form of a single digit times an integer power of 10, we need to move the decimal point until there is only one non-zero digit to the left of it.
Starting with 7,803,100, we can move the decimal point four places to the left to get 780,310.0, with one non-zero digit (7) to the left of the decimal point.
Since we have moved the decimal point four places to the left, the number can be expressed as 7.8031 × 10^6.
Rounding to the nearest place value, the final expression for 7,803,100 is 7.8 × 10^6.
To express the number of tourists (7,803,100) in the form of a single digit times an integer power of 10, we need to find a number between 1 and 10 and a power of 10 that will give us the closest value.
First, let's examine the magnitude of the number 7,803,100. It has 7 digits, which means we can express it as a single-digit number multiplied by 10 raised to a power of 6.
Next, let's look at the value of the single-digit number. The first digit of 7,803,100 is 7, so we can use that as our single-digit number.
Therefore, the number of tourists, 7,803,100, can be expressed as 7 × 10^6.
To express a large number in the form of a single digit times an integer power of 10, follow these steps:
Step 1: Determine the significant digit of the number. In this case, the significant digit is the first digit of the given number, which is 7.
Step 2: Count the number of digits in the given number. In this case, the given number has 7 digits.
Step 3: Determine the exponent of 10 by subtracting 1 from the number of digits. In this case, 7 - 1 = 6.
Step 4: Write the number in the form of a single digit times 10 raised to the power of the exponent. The result is 7.8 x 10^6.
Therefore, rounding the nearest place value, the number of tourists visiting country A from 2018 to 2020 can be expressed as 7.8 million.
