Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It is commonly used in mathematics, physics, and engineering to simplify complex calculations. In this article, we will explore the correct way to represent 5600 L using scientific notation.

What is Scientific Notation?

Scientific notation is a method of expressing numbers as a product of a number between 1 and 10 and a power of 10. The general form of scientific notation is:

a × 10^n

where a is the coefficient and n is the exponent. The coefficient is a number between 1 and 10, and the exponent is a positive or negative integer.

Representing 5600 L in Scientific Notation

To represent 5600 L in scientific notation, we need to express it as a product of a number between 1 and 10 and a power of 10. We can start by breaking down 5600 into a number between 1 and 10 and a multiple of 10.

Step 1: Break Down 5600

We can break down 5600 as follows:

5600 = 5.6 × 1000

Step 2: Express 1000 as a Power of 10

We can express 1000 as a power of 10 as follows:

1000 = 10^3

Step 3: Write the Scientific Notation

Now we can write 5600 L in scientific notation as:

5.6 × 10^3 L

Is the Answer Correct?

Yes, the answer is correct. The correct way to represent 5600 L using scientific notation is indeed:

5.6 × 10^3 L

Why is the Answer Correct?

The answer is correct because it follows the rules of scientific notation. The coefficient (5.6) is a number between 1 and 10, and the exponent (3) is a positive integer. This makes it a valid scientific notation.

What are the Other Options?

Let's take a look at the other options:

A. $-5.6 \times 10^3 \, \text{L}$

B. $-5.6 \times 10^{-3} \, \text{L}$

C. $5.6 \times 10^{-3} \, \text{L}$

D. $5.6 \times 10^{-3} \, \text{L}$

Option A: Negative Coefficient

Option A has a negative coefficient (-5.6). This is incorrect because the coefficient should be a number between 1 and 10, not negative.

Option B: Negative Exponent

Option B has a negative exponent (-3). This is incorrect because the exponent should be a positive integer, not negative.

Option C: Negative Exponent

Option C has a negative exponent (-3). This is incorrect for the same reason as Option B.

Option D: Negative Exponent

Option D has a negative exponent (-3). This is incorrect for the same reason as Options B and C.

Conclusion

In conclusion, the correct way to represent 5600 L using scientific notation is:

5.6 × 10^3 L

This follows the rules of scientific notation, with a coefficient between 1 and 10 and a positive exponent. The other options are incorrect because they violate these rules.
