What is Scientific Notation?

Scientific notation is a way of expressing very large or very small numbers in a more manageable form. It involves expressing a number as a product of a number between 1 and 10 and a power of 10. For example, the number 456,000 can be expressed in scientific notation as 4.56 × 10^5.

Multiplying with Scientific Notation

When multiplying numbers in scientific notation, we multiply the coefficients (the numbers in front of the powers of 10) and add the exponents of the powers of 10. This is based on the rule that a × b^c = a × b × b × ... × b (c times).

Step 1: Multiply the Coefficients

To multiply the coefficients, we simply multiply the numbers together.

5.86 × 3.1 = 18.166

Step 2: Add the Exponents

To add the exponents, we need to make sure that the bases are the same. In this case, the bases are both 10, so we can simply add the exponents.

-7 + 4 = -3

Step 3: Write the Product in Scientific Notation

Now that we have the product of the coefficients and the sum of the exponents, we can write the product in scientific notation.

18.166 × 10^(-3)

However, we need to make sure that the coefficient is between 1 and 10. To do this, we can move the decimal point of the coefficient to the left until it is between 1 and 10.

18.166 → 1.8166

We also need to adjust the exponent to reflect the fact that we moved the decimal point.

-3 + 1 = -2

So, the product in scientific notation is:

1.8166 × 10^(-2)

Real-World Applications of Multiplying with Scientific Notation

Multiplying with scientific notation has many real-world applications, particularly in fields such as physics, engineering, and chemistry. For example, scientists and engineers often need to calculate the product of very large or very small numbers, such as the product of the distance between two objects and the force exerted on them.

Example 1: Calculating the Product of Distance and Force

Suppose we want to calculate the product of the distance between two objects (5.86 × 10^(-7) meters) and the force exerted on them (3.1 × 10^4 Newtons).

Using the rules of multiplying with scientific notation, we can calculate the product as follows:

(5.86 × 10^(-7)) × (3.1 × 10^4) = 18.166 × 10^(-3)

However, we need to make sure that the coefficient is between 1 and 10. To do this, we can move the decimal point of the coefficient to the left until it is between 1 and 10.

18.166 → 1.8166

We also need to adjust the exponent to reflect the fact that we moved the decimal point.

-3 + 1 = -2

So, the product in scientific notation is:

1.8166 × 10^(-2)

Example 2: Calculating the Product of Time and Speed

Suppose we want to calculate the product of the time it takes for an object to travel a certain distance (5.86 × 10^(-7) seconds) and the speed of the object (3.1 × 10^4 meters per second).

Using the rules of multiplying with scientific notation, we can calculate the product as follows:

(5.86 × 10^(-7)) × (3.1 × 10^4) = 18.166 × 10^(-3)

However, we need to make sure that the coefficient is between 1 and 10. To do this, we can move the decimal point of the coefficient to the left until it is between 1 and 10.

18.166 → 1.8166

We also need to adjust the exponent to reflect the fact that we moved the decimal point.

-3 + 1 = -2

So, the product in scientific notation is:

1.8166 × 10^(-2)
