Q. Assuming x and y are both positive, write the following expression in simplest radical form.y328x4y6Answer:
Express in Exponential Form: First, let's express the square root in exponential form and then combine the exponents.28x4y6=(28x4y6)21Now we can multiply the exponents outside the radical by the exponents inside the radical.y3⋅(28x4y6)21
Simplify Inside the Radical: Next, we need to simplify the expression inside the radical. 28=4×7, and 4 is a perfect square, so we can take the square root of 4. (28x4y6)1/2=(4×7×x4×y6)1/2=(22×7×x4×y6)1/2=2×7×x4/2×y6/2=2×7×x2×y3
Combine Terms with Same Base: Now we can combine the terms with the same base using the product rule of exponents.y3×2×7×x2×y3= 2×7×x2×y3+3= 2×7×x2×y6
Final Simplification: Finally, we have simplified the expression to its simplest radical form.
