Q. Simplify. Assume all variables are positive.\newliner34r94r34\frac{r^{\frac{3}{4}}}{r^{\frac{9}{4}} \cdot r^{\frac{3}{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. Identify Properties: Write down the expression and identify the properties to use.\newlineWe have the expression r34/(r94r34)r^{\frac{3}{4}} / (r^{\frac{9}{4}} * r^{\frac{3}{4}}). We will use the properties of exponents to simplify this expression.
  2. Combine Exponents: Combine the exponents in the denominator using the product of powers property.\newlineThe product of powers property states that am×an=am+na^m \times a^n = a^{m+n} when the bases are the same. So, we combine the exponents in the denominator:\newliner94×r34=r94+34=r124=r3r^{\frac{9}{4}} \times r^{\frac{3}{4}} = r^{\frac{9}{4} + \frac{3}{4}} = r^{\frac{12}{4}} = r^3.
  3. Rewrite Expression: Rewrite the original expression with the simplified denominator.\newlineNow we have r34/r3r^{\frac{3}{4}} / r^{3}.
  4. Simplify Using Quotient of Powers: Simplify the expression using the quotient of powers property.\newlineThe quotient of powers property states that am/an=amna^m / a^n = a^{m-n} when the bases are the same. So, we subtract the exponents:\newliner34/r3=r343=r34124=r94r^{\frac{3}{4}} / r^3 = r^{\frac{3}{4} - 3} = r^{\frac{3}{4} - \frac{12}{4}} = r^{-\frac{9}{4}}.
  5. Make Exponent Positive: Since we want all exponents to be positive, we rewrite the expression with a positive exponent.\newlineTo make the exponent positive, we take the reciprocal of the base:\newliner(9/4)=1/r(9/4)r^{(-9/4)} = 1 / r^{(9/4)}.
