Q. Which expressions are equivalent to x45 x^{\frac{4}{5}} ?\newlineChoose all answers that apply:\newlineA (x4)5 (\sqrt[4]{x})^{5} \newlineB x145 \sqrt[5]{x^{\frac{1}{4}}} \newlineC (x4)5 \left(x^{4}\right)^{5} \newlineD None of the above
  1. Understanding exponents: Understand the properties of exponents. The expression x45x^{\frac{4}{5}} can be rewritten using the property of exponents that states xab=(xb)ax^{\frac{a}{b}} = (\sqrt[b]{x})^a.
  2. Applying property to option A: Apply the property to option A.\newlineOption A is (x4)5(\sqrt[4]{x})^5. According to the property, this is equivalent to x54x^{\frac{5}{4}}, which is not the same as x45x^{\frac{4}{5}}.
  3. Applying property to option B: Apply the property to option B.\newlineOption B is x145\sqrt[5]{x^{\frac{1}{4}}}. This can be rewritten as (x14)15(x^{\frac{1}{4}})^{\frac{1}{5}}, which according to the property of exponents (xa)b=xab(x^{a})^{b} = x^{a*b}, is x(14)(15)=x120x^{(\frac{1}{4})*(\frac{1}{5})} = x^{\frac{1}{20}}, which is not the same as x45x^{\frac{4}{5}}.
  4. Applying property to option C: Apply the property to option C.\newlineOption C is (x4)5(x^4)^5. According to the property of exponents (xa)b=xab(x^a)^b = x^{a*b}, this is x45=x20x^{4*5} = x^{20}, which is not the same as x45x^{\frac{4}{5}}.
  5. Determining equivalent options: Determine if any of the options are equivalent to x45x^{\frac{4}{5}}. None of the options AA, BB, or CC are equivalent to x45x^{\frac{4}{5}}, so the correct answer is DD, None of the above.
