  1. Recognize Imaginary Unit: First, we need to recognize that the square root of a negative number involves the imaginary unit ii, where i2=1i^2 = -1. So, we can rewrite the square root of 36-36 as 6i6i.
  2. Find Square Root of x11x^{11}: Next, we need to find the square root of x11x^{11}. Since the exponent is odd, we cannot directly take the square root. However, we can express x11x^{11} as x10×xx^{10} \times x, and then take the square root of x10x^{10} which is an even exponent.
  3. Find Square Root of y8y^{8}: The square root of x10x^{10} is x10/2=x5x^{10/2} = x^5. We still have the xx that was not under the square root, so we need to multiply x5x^5 by the square root of xx, which gives us x5+1/2=x11/2x^{5 + 1/2} = x^{11/2}.
  4. Combine Parts: Now, we need to find the square root of y8y^{8}. Since the exponent is even, we can directly take the square root. The square root of y8y^{8} is y8/2=y4y^{8/2} = y^4.
  5. Compare with Options: Combining all the parts together, we have 6i×x(11/2)×y46i \times x^{(11/2)} \times y^4. This gives us the expression 6ix(112)y46ix^{\left(\frac{11}{2}\right)}y^{4}.
  6. Compare with Options: Combining all the parts together, we have 6i6i times x(11/2)x^{(11/2)} times y4y^4. This gives us the expression 6ix(112)y46ix^{\left(\frac{11}{2}\right)}y^{4}.We can now compare the expression we found with the options given in the problem. The correct expression that matches our result is 6ix(112)y46ix^{\left(\frac{11}{2}\right)}y^{4}.
