Math Problem Statement

Bentuk sederhana dari \(\frac{8x^{-2}y^5z^2}{4x^{-3}y^3z^3}\) adalah?

Solution

The given mathematical expression is:

8x2y5z24x3y3z3\frac{8x^{-2}y^5z^2}{4x^{-3}y^3z^3}

Step 1: Simplify the coefficients

The numerical coefficients are 84=2\frac{8}{4} = 2.

Step 2: Simplify the variables

  • For xx, we apply the rule for dividing exponents: xaxb=xab\frac{x^a}{x^b} = x^{a-b}. So: x2x3=x2(3)=x1\frac{x^{-2}}{x^{-3}} = x^{-2 - (-3)} = x^{1}

  • For yy, similarly: y5y3=y53=y2\frac{y^5}{y^3} = y^{5-3} = y^2

  • For zz: z2z3=z23=z1=1z\frac{z^2}{z^3} = z^{2-3} = z^{-1} = \frac{1}{z}

Step 3: Combine the results

Now we combine the simplified terms:

2x1y21z=2xy2z2x^1y^2 \cdot \frac{1}{z} = \frac{2xy^2}{z}

Final Answer:

The simplified form is 2xy2z\frac{2xy^2}{z}, which corresponds to option e.

Would you like more details or have any questions?

Here are 5 related questions to expand your understanding:

  1. How would the expression change if the exponents were negative for both the numerator and denominator?
  2. What are the rules for dividing variables with exponents?
  3. How can you generalize this approach for any expression involving exponents and division?
  4. How does the rule for negative exponents work when simplifying such fractions?
  5. How would the expression look if there were no negative exponents?

Tip: Always remember that when dividing powers with the same base, subtract the exponents!
