Read and write the number in two other forms 70,000,000 + 8,000,000+20,000+8
The Correct Answer and Explanation is:
To write the number (70,000,000 + 8,000,000 + 20,000 + 8) in two other forms, we first need to calculate the sum of these numbers.
Calculation:
- Add the values:
[
70,000,000 + 8,000,000 + 20,000 + 8 = 78,020,008
]
Writing the Number in Different Forms:
- Standard Form:
- The standard form is the usual way of writing numbers using digits. The standard form of the calculated sum is:
[
78,020,008
]
- Expanded Form:
- The expanded form breaks the number down into its individual place values. The expanded form for (78,020,008) can be written as:
[
70,000,000 + 8,000,000 + 20000 + 8
] - Here, each part represents the value of each digit based on its position in the number. For example, (70,000,000) represents the (7) in the hundred million place, (8,000,000) represents the (8) in the ten million place, (20,000) represents the (2) in the thousand place, and (8) represents the (8) in the ones place.

Explanation:
Understanding how to express numbers in different forms is essential in mathematics as it helps in visualizing and comprehending the value of numbers. The standard form is most commonly used in calculations and day-to-day contexts, while the expanded form aids in understanding the contributions of each digit to the total value of the number. This comprehension is crucial when performing operations such as addition or subtraction, especially when dealing with larger numbers. Additionally, expressing numbers in word form is particularly helpful in formal writing or documentation where numerical clarity is required. Overall, mastering these forms enhances numerical literacy and aids in effective communication in mathematics.
