Q. Express the following fraction in simplest form using only positive exponents.\newline3w93(w3)5 \frac{3 w^{9}}{3\left(w^{3}\right)^{5}} \newlineAnswer:
  1. Write & Identify Properties: Write down the given expression and identify the properties of exponents that can be applied.\newlineGiven expression: (3w9)/(3(w3)5)(3w^{9})/(3(w^{3})^{5})\newlineWe can apply the power of a power property for the denominator, which states that (am)n=amn(a^{m})^{n} = a^{m*n}.
  2. Apply Power of Power: Apply the power of a power property to the denominator.\newline(3(w3)5)=3×w3×5=3×w15(3(w^{3})^{5}) = 3 \times w^{3\times5} = 3 \times w^{15}
  3. Rewrite with Simplified Denominator: Rewrite the original expression with the simplified denominator.\newline(3w9)/(3(w3)5)=(3w9)/(3w15)(3w^{9})/(3(w^{3})^{5}) = (3w^{9})/(3 \cdot w^{15})
  4. Simplify by Canceling Factors: Simplify the expression by canceling out common factors in the numerator and the denominator.\newlineThe common factor of 33 in the numerator and denominator can be canceled out, and we can use the quotient of powers property for the ww terms, which states that am/an=amna^{m}/a^{n} = a^{m-n} when a0a \neq 0.\newline(3w9)/(3w15)=w915=w6(3w^{9})/(3 \cdot w^{15}) = w^{9-15} = w^{-6}
  5. Rewrite with Positive Exponents: Since we need the expression with only positive exponents, we rewrite w6w^{-6} using the property an=1ana^{-n} = \frac{1}{a^n}.\newlinew6=1w6w^{-6} = \frac{1}{w^6}
