Introduction

In mathematics, exponential notation is a powerful tool used to represent very large or very small numbers in a concise and manageable way. However, when dealing with exponential notations, it's essential to understand the rules governing their comparison. In this article, we'll delve into the world of exponential notations and explore which sign makes the statement true: $1,027,000,000 \times 10^{-15} \, ? \, 1.027 \times 10^{-6}$.

Understanding Exponential Notations

Exponential notation is a shorthand way of expressing numbers in terms of a base raised to a power. The general form of an exponential notation is $a \times 10^b$, where $a$ is the coefficient and $b$ is the exponent. For example, $1,027,000,000 \times 10^{-15}$ can be written as $1.027 \times 10^{12}$.

Comparing Exponential Notations

When comparing exponential notations, we need to consider the magnitude of the numbers. The magnitude of a number is its absolute value, ignoring any negative signs. In the given statement, we have two exponential notations: $1,027,000,000 \times 10^{-15}$ and $1.027 \times 10^{-6}$.

To compare these numbers, we need to express them in the same form. We can do this by converting the first number to a decimal notation. To convert $1,027,000,000 \times 10^{-15}$ to a decimal notation, we need to multiply the coefficient by the base raised to the power of the exponent.

Converting Exponential Notation to Decimal Notation

To convert $1,027,000,000 \times 10^{-15}$ to a decimal notation, we need to multiply the coefficient by the base raised to the power of the exponent.

$$1,027,000,000 \times 10^{-15} = 1.027 \times 10^{12}$$

Now that we have both numbers in the same form, we can compare them.

Comparing the Numbers

To compare the numbers, we need to consider their magnitudes. The magnitude of a number is its absolute value, ignoring any negative signs.

$$|1.027 \times 10^{12}| = 1.027 \times 10^{12}$$

$$|1.027 \times 10^{-6}| = 1.027 \times 10^{-6}$$

Since $1.027 \times 10^{12}$ is greater than $1.027 \times 10^{-6}$, we can conclude that the statement is true.

Conclusion

In conclusion, when comparing exponential notations, we need to consider the magnitude of the numbers. By converting the numbers to decimal notation and comparing their magnitudes, we can determine which sign makes the statement true. In this case, the statement is true because $1,027,000,000 \times 10^{-15}$ is greater than $1.027 \times 10^{-6}$.

Answer

The correct answer is A. >.

Additional Examples

Here are some additional examples to illustrate the concept:

• $4,000,000 \times 10^{-9} \, ? \, 4 \times 10^{-3}$
• $9,000,000,000 \times 10^{-12} \, ? \, 9 \times 10^{-6}$
• $6,000,000,000 \times 10^{-15} \, ? \, 6 \times 10^{-9}$

In each of these examples, we need to convert the exponential notation to a decimal notation and compare the magnitudes of the numbers.

Conclusion

In conclusion, comparing exponential notations requires a deep understanding of the rules governing their comparison. By converting the numbers to decimal notation and comparing their magnitudes, we can determine which sign makes the statement true. In this article, we've explored the concept of comparing exponential notations and provided additional examples to illustrate the concept.
