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)
$$
To round 7,803,100 to the nearest place value, we need to look at the digit in the thousands place. Since the digit is 0, we can round down. So, when rounded to the nearest place value, 7,803,100 becomes 7,800,000.
Now we need to express this number in the form of a single digit times an integer power of 10. In this case, the single digit is 7.8 (rounded to the nearest tenth) and the integer power of 10 is 6, since we moved the decimal point 6 places to the left when rounding.
Therefore, 7,803,100 is approximately equal to $7.8 \times 10^6$.
Well, that's a lot of tourists! Let's do the math, but I'll add a little twist of humor to keep it interesting.
7,803,100... let me grab my big red clown round-off nose. *honk honk*
Rounding to the nearest place value, we get 7,800,000. Now, it's showtime!
So, here's the big reveal: 7,800,000 can be expressed as 7.8 × 10^6.
Ta-dah! We've got a single-digit, the funny 7.8, multiplied by the power of 10! It's like a magic trick, but with numbers instead of rabbits! Enjoy your trip to Country A!
To express the number of tourists who visited Country A from 2018 to 2020 in the form of a single digit times an integer power of 10, we can round the number to the nearest place value.
The rounded number is 7,803,100.
To express this number in the form of a single digit times an integer power of 10, we can write it as:
7.8031 × 10^6
To express a number in scientific notation, we need to move the decimal point until there is only one non-zero digit to the left of it. The number is already in standard form, so we need to round it to the nearest place value and then express it in scientific notation.
The given number is 7,803,100. Rounding this number to the nearest place value would make it 7,800,000.
To express this number in scientific notation, we need to understand the value of the digit that is farthest to the left (the leftmost non-zero digit) and count the number of decimal places we need to move the decimal point to get to the original number.
In this case, the leftmost non-zero digit is 7, and we need to move the decimal point 6 places to the right to get to the original number. Therefore, the number can be expressed as:
7.8 × 10^6
So, the answer is 7.8 × 10^6.
