The product rule of exponents is one of the fundamental rules for dealing with exponents in algebra. It states that when you multiply two expressions that have the same base, you can add the exponents. Here's how you can apply the product rule step by step:
Given two expressions with the same base:
a^m * a^n,
Where:
- a is the base,
- m and n are the exponents.
Step 1: Verify the base is the same
Make sure that both expressions have the same base before you use the product rule. The rule only applies to expressions with the same base.
Step 2: Add the exponents
The rule states that you add the exponents together:
a^m * a^n = a^(m + n).
Step 3: Simplify
Once you have added the exponents, rewrite the expression as a single exponentiation.
Let's go through an example to illustrate the process:
Example:
(3^2) * (3^5),
Both expressions have the same base (3), so we can use the product rule.
Using the product rule, we add the exponents:
2 + 5 = 7.
So, we can write:
(3^2) * (3^5) = 3^(2 + 5) = 3^7.
That's the simplified result of using the product rule on this example.
Remember that the product rule of exponents only applies to multiplication of expressions with the same base. For division, there's a different rule called the quotient rule of exponents, where you subtract the exponent of the denominator from the exponent of the numerator if you have the same base. For example:
a^m / a^n = a^(m - n).
And that's how you use the product rule of exponents.

a^m * a^n,

- m and n are the exponents.

To find the numerical equivalent of an expression with exponents, you simply calculate the value of the expression by raising the base to the power of the exponent. Here's how to do it:
Given an expression:
a^n
To find the numerical equivalent:
Step 1: Recognize the base (a) and the exponent (n).
Step 2: Use the exponentiation operation, which means multiplying the base by itself n times.
For example, to find the numerical equivalent of 3^4:
3^4 means that you need to multiply 3 by itself 4 times:
3 * 3 * 3 * 3 = 81.
So the numerical equivalent of 3^4 is 81.
You can perform this calculation manually if the numbers are small and the exponent is manageable, or you can use a calculator for larger numbers or higher exponents. Most scientific calculators have an exponentiation button, usually labeled as "^", "exp", or "y^x".
When using a calculator, simply enter the base, press the exponentiation button, then enter the exponent and hit equals. For example:
- Enter "3"
- Press the "^" or "exp" or "y^x" button
- Enter "4"
- Press "="
The calculator will display the numerical equivalent, which is 81 in this example.
This method works for all expressions with whole number exponents. If the exponent is a fraction, it represents a root, and if the exponent is negative, it represents taking the reciprocal (inverse) of the base to the positive exponent. Ensure your calculator is set to the correct mode (degree or radian) if the base or exponent involves trigonometric functions or if you are dealing with complex numbers.

When you have two expressions with exponents and you want to find the numerical equivalent of their product or quotient, you can follow these steps:
For the product of two expressions (using the product rule):
Step 1: Make sure the bases of the expressions are the same.
Step 2: Add the exponents if the bases are the same.
Step 3: Calculate the numerical equivalent by raising the common base to the new exponent.
For example:
To find the numerical equivalent of (2^3) * (2^4):
Step 1: Recognize that both expressions have the same base (2).
Step 2: Apply the product rule: 2^(3+4) = 2^7
Step 3: Calculate 2^7: 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
The numerical equivalent of (2^3) * (2^4) is 128.
For the quotient of two expressions (using the quotient rule):
Step 1: Make sure the bases of the expressions are the same.
Step 2: Subtract the exponent of the denominator from the exponent of the numerator.
Step 3: Calculate the numerical equivalent by raising the common base to the new exponent.
For example:
To find the numerical equivalent of (2^5) / (2^2):
Step 1: Recognize that both expressions have the same base (2).
Step 2: Apply the quotient rule: 2^(5-2) = 2^3
Step 3: Calculate 2^3: 2 * 2 * 2 = 8
The numerical equivalent of (2^5) / (2^2) is 8.
Remember, you can always use a calculator to perform exponentiation when dealing with larger numbers or higher powers. Just use the calculator's exponentiation function for each expression, then multiply or divide the resulting values as appropriate.
If the expressions have different bases and you want to multiply them together or divide them, you would simply need to find the numerical equivalent of each one separately, and then perform the multiplication or division.
Example of expressions with different bases (to be multiplied):
To find the numerical equivalent of (3^2) * (5^3):
Calculate each part:
3^2 = 9
5^3 = 125
Multiply the results:
9 * 125 = 1125
So the numerical equivalent of (3^2) * (5^3) is 1125.
For the product of two expressions (using the product rule):
Step 1: Make sure the bases of the expressions are the same.
Step 2: Add the exponents if the bases are the same.
Step 3: Calculate the numerical equivalent by raising the common base to the new exponent.
For example:
To find the numerical equivalent of (2^3) * (2^4):
Step 1: Recognize that both expressions have the same base (2).
Step 2: Apply the product rule: 2^(3+4) = 2^7
Step 3: Calculate 2^7: 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128
The numerical equivalent of (2^3) * (2^4) is 128.
