Introduction to Simplifying Algebraic Expressions

Simplifying algebraic expressions is a crucial skill in mathematics, particularly in algebra and calculus. It involves rewriting complex expressions in a simpler form, often by combining like terms, canceling out common factors, or using properties of exponents. In this article, we will focus on simplifying the given expression 5x⋅25x−15⋅125x\frac{5^x \cdot 25^{x-1}}{5 \cdot 125^x} using various techniques and properties of exponents.

Understanding the Properties of Exponents

Before we dive into simplifying the expression, it's essential to understand the properties of exponents. The properties of exponents state that:

  • When multiplying two powers with the same base, we add their exponents.
  • When dividing two powers with the same base, we subtract their exponents.
  • When raising a power to another power, we multiply their exponents.

These properties will be crucial in simplifying the given expression.

Simplifying the Expression

To simplify the expression 5x⋅25x−15⋅125x\frac{5^x \cdot 25^{x-1}}{5 \cdot 125^x}, we can start by rewriting the expression using the properties of exponents.

5x⋅25x−15⋅125x\frac{5^x \cdot 25^{x-1}}{5 \cdot 125^x}

We can rewrite 2525 as 525^2 and 125125 as 535^3.

5x⋅(52)x−15⋅(53)x\frac{5^x \cdot (5^2)^{x-1}}{5 \cdot (5^3)^x}

Using the property of exponents that (am)n=amn(a^m)^n = a^{mn}, we can simplify the expression further.

5x⋅52(x−1)5⋅53x\frac{5^x \cdot 5^{2(x-1)}}{5 \cdot 5^{3x}}

Now, we can use the property of exponents that amâ‹…an=am+na^m \cdot a^n = a^{m+n} to combine the exponents.

5x⋅52x−25⋅53x\frac{5^x \cdot 5^{2x-2}}{5 \cdot 5^{3x}}

Simplifying the exponents, we get:

5x+2x−25⋅53x\frac{5^{x+2x-2}}{5 \cdot 5^{3x}}

Combining the exponents, we get:

53x−25⋅53x\frac{5^{3x-2}}{5 \cdot 5^{3x}}

Now, we can use the property of exponents that aman=am−n\frac{a^m}{a^n} = a^{m-n} to simplify the expression further.

53x−25⋅53x\frac{5^{3x-2}}{5 \cdot 5^{3x}}

Simplifying the expression, we get:

53x−251+3x\frac{5^{3x-2}}{5^{1+3x}}

Using the property of exponents that aman=am−n\frac{a^m}{a^n} = a^{m-n}, we can simplify the expression further.

5(3x−2)−(1+3x)5^{(3x-2)-(1+3x)}

Simplifying the exponents, we get:

5−25^{-2}

Therefore, the simplified expression is 5−2\boxed{5^{-2}}.

In this article, we simplified the expression 5x⋅25x−15⋅125x\frac{5^x \cdot 25^{x-1}}{5 \cdot 125^x} using various techniques and properties of exponents. We rewrote the expression using the properties of exponents, combined like terms, and canceled out common factors to arrive at the simplified expression 5−2\boxed{5^{-2}}. This example demonstrates the importance of understanding the properties of exponents and applying them to simplify complex expressions.
