Make y the subject of the formula Z = x(^2) + (frac{1}{y^3})

Make y the subject of the formula Z = x(^2) + (frac{1}{y^3})

  • A.
    y = (frac{1}{(Z – x^2)^3})
  • B.
    y = (frac{1}{(Z + x^2)^{frac{1}{3}}})
  • C.
    y = (frac{1}{(Z – x^2)^{frac{1}{3}}})
  • D.
    y = (frac{1}{sqrt[3]{Z} – sqrt[3]{x^2}})
Correct Answer: Option C
Explanation

Z = x(^2) + (frac{1}{y^3})
Z – x(^2) = (frac{1}{y^3})
y(^3) = (frac{1}{Z – x^2})
y = (sqrt[3]{frac{1}{Z – x^2}})
∴ y = (frac{1}{sqrt[3]{Z – x^2}})

y = (frac{1}{(Z – x^2)^{frac{1}{3}}})
