Q. Simplify. Assume all variables are positive.\newliner74r74r74\frac{r^{\frac{7}{4}}}{r^{\frac{7}{4}} \cdot r^{\frac{7}{4}}}\newlineWrite your answer in the form AA or AB\frac{A}{B}, where AA and BB are constants or variable expressions that have no variables in common. All exponents in your answer should be positive.\newline______
  1. Write Quotient Rule: Write down the expression and apply the quotient rule for exponents. The quotient rule states that when dividing like bases, you subtract the exponents. r74/(r74r74)r^{\frac{7}{4}} / (r^{\frac{7}{4}} \cdot r^{\frac{7}{4}})
  2. Apply Product Rule: Apply the product rule for exponents to the denominator.\newlineThe product rule states that when multiplying like bases, you add the exponents.\newliner74/r74+74r^{\frac{7}{4}} / r^{\frac{7}{4} + \frac{7}{4}}
  3. Simplify Denominator: Simplify the exponent in the denominator.\newline74+74=144\frac{7}{4} + \frac{7}{4} = \frac{14}{4}\newliner74/r144r^{\frac{7}{4}} / r^{\frac{14}{4}}
  4. Convert Exponent: Convert the exponent in the denominator to a simplified form. \newline144\frac{14}{4} can be simplified to 3.53.5 or 72\frac{7}{2}.\newliner74r72\frac{r^{\frac{7}{4}}}{r^{\frac{7}{2}}}
  5. Subtract Exponents: Subtract the exponents using the quotient rule.\newline(74)(72)=(74)(144)=74(\frac{7}{4}) - (\frac{7}{2}) = (\frac{7}{4}) - (\frac{14}{4}) = -\frac{7}{4}\newliner(74)r^{(-\frac{7}{4})}
  6. Use Negative Exponents: Since we want the exponent to be positive, we can rewrite the expression using the property of negative exponents.\newlineA negative exponent means that the base is on the wrong side of the fraction line, so we flip the base to the other side.\newliner(7/4)=1/r(7/4)r^{(-7/4)} = 1 / r^{(7/4)}
  7. Final Answer: Write the final answer in the form AA or A/BA/B as requested.\newlineThe final answer is in the form of 1/B1 / B, where BB is r7/4r^{7/4}.\newline1/r7/41 / r^{7/4}
