Solve The Equation: $\[ 6^{-2a} = 6^{2-3a} \\]
Introduction
When it comes to solving equations involving exponents, it's essential to understand the properties of exponents and how to manipulate them to isolate the variable. In this article, we will focus on solving the equation 6^(-2a) = 6^(2-3a) using algebraic techniques.
Understanding Exponents
Before we dive into solving the equation, let's review the basics of exponents. An exponent is a small number that is raised to the power of a larger number. For example, 6^2 means 6 squared, or 6 multiplied by itself 2 times. The exponent can be positive, negative, or even a fraction.
Properties of Exponents
There are several properties of exponents that we need to know when solving equations involving exponents. These properties include:
- Product of Powers: When multiplying two numbers with the same base, we add the exponents. For example, 6^2 * 6^3 = 6^(2+3) = 6^5.
- Power of a Power: When raising a number with an exponent to another power, we multiply the exponents. For example, (62)3 = 6^(2*3) = 6^6.
- Quotient of Powers: When dividing two numbers with the same base, we subtract the exponents. For example, 6^3 / 6^2 = 6^(3-2) = 6^1.
Solving the Equation
Now that we have reviewed the properties of exponents, let's focus on solving the equation 6^(-2a) = 6^(2-3a). To solve this equation, we need to use the property of exponents that states that if two numbers with the same base are equal, then their exponents must be equal.
Setting Up the Equation
We can set up the equation by equating the exponents:
-2a = 2-3a
Isolating the Variable
To isolate the variable, we need to get all the terms with the variable on one side of the equation. We can do this by adding 3a to both sides of the equation:
-2a + 3a = 2
Simplifying the Equation
Now that we have isolated the variable, we can simplify the equation by combining like terms:
a = 2
Conclusion
In this article, we have solved the equation 6^(-2a) = 6^(2-3a) using algebraic techniques. We have reviewed the properties of exponents and used them to set up and solve the equation. The final solution is a = 2.
