Q. Given x>0 and y>0, select the expression that is equivalent to−36x4y10−6x21y516ix2y5−6x2y56ix21y51
Identify Given Expression: Identify the given expression and the mathematical operation to be performed.We need to find the equivalent expression for −36x4y10.
Use Imaginary Unit: Recognize that the square root of a negative number involves the imaginary unit 'i', where i2=−1. Therefore, −36x4y10 can be written as i⋅36x4y10.
Simplify Positive Terms: Simplify the square root of the positive part of the expression.Since 36, x4, and y10 are all perfect squares, we can take the square root of each term separately.36x4y10=36×x4×y10.
Calculate Square Roots: Calculate the square root of each term.36=6, x4=x24=x2, and y10=y210=y5.So, 36x4y10=6×x2×y5.
Combine Results: Combine the results from the previous steps to get the final expression.The equivalent expression is i×6×x2×y5, which can be written as 6ix2y5.
