Rewrite using a single exponent. – Rewrite using a single exponent is a powerful technique that allows us to simplify complex expressions and make them more manageable. This process involves expressing multiple exponents as a single, combined exponent, providing numerous benefits in various mathematical applications.
By understanding the methods and benefits of rewriting using a single exponent, we can enhance our mathematical skills and gain a deeper understanding of algebraic concepts.
Understanding Rewrite Using a Single Exponent
Rewriting an expression using a single exponent involves expressing a complex expression with multiple exponents as a single, simplified exponent. This process simplifies calculations and makes expressions more manageable.
To rewrite using a single exponent, follow these steps:
- Identify the base and the exponents of each term.
- Multiply the exponents of terms with the same base.
- Combine the bases by multiplying them.
For example, (x 2y 3) 4can be rewritten as x 8y 12.
Methods for Rewriting Using a Single Exponent
Using Laws of Exponents:
Apply laws of exponents, such as (a m) n= a mn, to combine exponents with the same base.
Factoring:
Factor out common terms to identify terms with the same base and exponents.
Example:
(x 2+ 2x)(x 2– 2x) = (x 2)(x 2) – (2x)(x 2) + (2x)(x) – (2x)(2x) = x 4– 2x 3+ 2x 2– 4x
Benefits of Rewriting Using a Single Exponent
Simplifies Calculations:
Combining exponents simplifies calculations by reducing the number of operations.
Makes Expressions More Manageable:
Rewriting expressions with a single exponent makes them easier to read, write, and understand.
Example:
Rewriting (2 3)(2 4)(2 5) as 2 12simplifies calculations and makes the expression more manageable.
Examples and Applications, Rewrite using a single exponent.
Example 1:
