Answer
Explanation:
Step1: Separate the coefficients and variables
Separate the coefficient - part $\frac{6}{8}$ and the variable - part $\frac{a^{2}}{a^{- 3}}\cdot\frac{b^{-2}}{b^{3}}$. $$\frac{6a^{2}b^{-2}}{8a^{-3}b^{3}}=\frac{6}{8}\cdot\frac{a^{2}}{a^{-3}}\cdot\frac{b^{-2}}{b^{3}}$$
Step2: Simplify the coefficient
Simplify $\frac{6}{8}$ to $\frac{3}{4}$. $$\frac{6}{8}=\frac{3}{4}$$
Step3: Use the quotient - rule of exponents for $a$
The quotient - rule of exponents is $\frac{x^{m}}{x^{n}}=x^{m - n}$. For $\frac{a^{2}}{a^{-3}}$, we have $a^{2-(-3)}=a^{2 + 3}=a^{5}$. $$\frac{a^{2}}{a^{-3}}=a^{2-(-3)}=a^{5}$$
Step4: Use the quotient - rule of exponents for $b$
For $\frac{b^{-2}}{b^{3}}$, we have $b^{-2-3}=b^{-5}=\frac{1}{b^{5}}$. $$\frac{b^{-2}}{b^{3}}=b^{-2 - 3}=b^{-5}$$
Step5: Combine the results
Multiply the simplified coefficient and variable parts together: $\frac{3}{4}\cdot a^{5}\cdot b^{-5}=\frac{3a^{5}b^{-5}}{4}$.
Answer:
$\frac{3a^{5}b^{-5}}{4}$
