Math Problem Statement

Simplify the expression \( \frac{x^{-5} \cdot x^3}{x^{-2}} \).

Solution

To solve the given expression:

x5x3x2\frac{x^{-5} \cdot x^3}{x^{-2}}

Step 1: Simplify the numerator

Using the property of exponents xaxb=xa+bx^a \cdot x^b = x^{a+b}:

x5x3=x5+3=x2.x^{-5} \cdot x^3 = x^{-5+3} = x^{-2}.

So, the numerator simplifies to x2x^{-2}.

Step 2: Simplify the fraction

The entire expression becomes:

x2x2.\frac{x^{-2}}{x^{-2}}.

Using the property of exponents xaxb=xab\frac{x^a}{x^b} = x^{a-b}:

x2(2)=x0.x^{-2-(-2)} = x^{0}.

Step 3: Simplify x0x^0

Any number (except 0) raised to the power of 0 equals 1. Thus:

x0=1.x^0 = 1.

Final Answer:

1\boxed{1}
