Q. Assuming x and y are both positive, write the following expression in simplest radical form.225x6y5Answer:
Simplify Product Inside Radical: We start by simplifying the square root of the product inside the radical. We know that the square root of a product is the product of the square roots, and we can also simplify the square root of a perfect square.225x6y5=225×x6×y5
Simplify Square Roots: Next, we simplify each square root separately. The square root of 25 is 5, the square root of x6 is x3 because (x3)2=x6, and the square root of y5 is y2y because (y2)2⋅y=y5.2⋅5⋅x3⋅y2⋅y
Multiply Constants and Like Terms: Now we multiply the constants and the like terms together. 2×5=1010×x3×y2×y
Write in Simplest Form: Finally, we write the expression in its simplest radical form. 10x3y2y
