Q. Given x>0 and y>0, select the expression that is equivalent to−100x13y8−10x26y16−10x213y410ix26y1610ix213y4
Identify Components: Identify the components of the expression inside the square root. The expression inside the square root is −100x13y8. We need to find the square root of this expression.
Factor Out −100: Factor out the square root of −100. The square root of −100 is the square root of 100 times the square root of −1, which is 10i, where i is the imaginary unit.
Determine Square Root of x13: Determine the square root of x13. To find the square root of x13, we raise x to the power of (13/2), because the square root is equivalent to raising to the power of 1/2.
Determine Square Root of y8: Determine the square root of y8. To find the square root of y8, we raise y to the power of (8/2), which simplifies to y4, because the square root of y8 is y8×1/2.
Combine Results: Combine the results from steps 2, 3, and 4. Combining the square root of −100, which is 10i, with the square root of x13, which is x(213), and the square root of y8, which is y4, we get the expression 10i×x(213)×y4.
Write Final Expression: Write the final expression.The equivalent expression for −100x13y8 is 10i×x(213)×y4.
