The answer is D. Here’s the explanation: Take out the constants: 20/4 x a^(-4)b(-3)c^(2) / a^(2)b^(-6)c^(5) Simplify the 20/4 to 5. Use the Quotient Rule which is x^a / x^b = x^(a-b) 5a^(-4-2)b(-3+6)c(2-5) Simplify (-4-2) to -6. Simplify (-3+6) to 3. Simplify (2-5) to -3. You’re left with 5a^(-6)b^(3)c^(-3) Use negative power rule which is x^(-a) = 1/x^(a) 5 x 1/a^(6)b^(3) x 1/c^(3) Final Answer: 5b^(3)/a^(6)c^(3)
