Simplify Each Expression Using the Properties of Powers

Understanding the Properties of Powers

When dealing with expressions that involve powers, it's essential to understand the properties of powers. The properties of powers are a set of rules that help us simplify expressions by combining or separating powers with the same base. In this article, we will focus on simplifying expressions using the properties of powers.

Property 1: Product of Powers

The product of powers property states that when we multiply two powers with the same base, we add the exponents. This property can be expressed as:

a^m * a^n = a^(m+n)

Simplifying the First Expression

Let's simplify the first expression: $2a^8 \cdot 2a^6$ . To simplify this expression, we will use the product of powers property.

Step 1: Multiply the Coefficients

The first step is to multiply the coefficients, which are the numbers in front of the variables. In this case, we have 2 multiplied by 2.

2 × 2 = 4

Step 2: Add the Exponents

The next step is to add the exponents. In this case, we have a^8 multiplied by a^6.

8 + 6 = 14

Step 3: Write the Simplified Expression

Now that we have multiplied the coefficients and added the exponents, we can write the simplified expression.

4a^14

Simplifying the Second Expression

Let's simplify the second expression: $4b^2 \cdot 8b^9$ . To simplify this expression, we will use the product of powers property.

Step 1: Multiply the Coefficients

The first step is to multiply the coefficients, which are the numbers in front of the variables. In this case, we have 4 multiplied by 8.

4 × 8 = 32

Step 2: Add the Exponents

The next step is to add the exponents. In this case, we have b^2 multiplied by b^9.

2 + 9 = 11

Step 3: Write the Simplified Expression

Now that we have multiplied the coefficients and added the exponents, we can write the simplified expression.

32b^11
