Q. Given x>0 x>0 and y>0 y>0 , select the expression that is equivalent to\newline64x12y93 \sqrt[3]{-64 x^{12} y^{9}} \newline4ix4y3 4 i x^{4} y^{3} \newline4ix9y6 4 i x^{9} y^{6} \newline4x9y6 -4 x^{9} y^{6} \newline4x4y3 -4 x^{4} y^{3}
  1. Simplify Constant Term: Simplify the cube root of the constant term.\newlineThe cube root of 64-64 is 4-4 because (4)3=64(-4)^3 = -64.
  2. Simplify Variable Term x12x^{12}: Simplify the cube root of the variable term x12x^{12}. The cube root of x12x^{12} is x123x^{\frac{12}{3}} because when taking the cube root, you divide the exponent by 33. So, x123=x4x^{\frac{12}{3}} = x^4.
  3. Simplify Variable Term y9y^{9}: Simplify the cube root of the variable term y9y^{9}. The cube root of y9y^{9} is y93y^{\frac{9}{3}} because when taking the cube root, you divide the exponent by 33. So, y93=y3y^{\frac{9}{3}} = y^{3}.
  4. Combine Results: Combine the results from Steps 11, 22, and 33. Combining the cube roots of the constant and variable terms, we get 4x4y3-4x^4y^3.
  5. Check Given Options: Determine if the result is one of the given options.\newlineThe result from Step 44 is 4x4y3-4x^4y^3, which matches one of the given options.
