Introduction

In this article, we will simplify the given expression 27x2y416yz3â‹…8z9xy3\frac{27 x^2 y^4}{16 y z^3} \cdot \frac{8 z}{9 x y^3}. This involves applying the rules of exponents and simplifying the resulting expression. We will break down the process into manageable steps, making it easier to understand and follow along.

Step 1: Multiply the Numerators and Denominators

To simplify the given expression, we need to multiply the numerators and denominators separately. The numerator of the first fraction is 27x2y427 x^2 y^4, and the numerator of the second fraction is 8z8 z. The denominator of the first fraction is 16yz316 y z^3, and the denominator of the second fraction is 9xy39 x y^3.

import sympy as sp

# Define the variables
x, y, z = sp.symbols('x y z')

# Define the expression
expr = (27*x**2*y**4)/(16*y*z**3) * (8*z)/(9*x*y**3)

# Simplify the expression
simplified_expr = sp.simplify(expr)

Step 2: Apply the Rules of Exponents

When multiplying fractions, we can add the exponents of the same base. We will apply this rule to simplify the expression.

# Apply the rules of exponents
simplified_expr = simplified_expr.simplify()

Step 3: Cancel Out Common Factors

After applying the rules of exponents, we can cancel out any common factors between the numerator and denominator.

# Cancel out common factors
simplified_expr = simplified_expr.cancel()

Step 4: Simplify the Expression

Now that we have applied the rules of exponents and canceled out common factors, we can simplify the expression further.

# Simplify the expression
simplified_expr = simplified_expr.simplify()

Conclusion

In this article, we simplified the given expression 27x2y416yz3â‹…8z9xy3\frac{27 x^2 y^4}{16 y z^3} \cdot \frac{8 z}{9 x y^3} using the rules of exponents and canceling out common factors. We broke down the process into manageable steps, making it easier to understand and follow along.
