Q. Assuming x and y are both positive, write the following expression in simplest radical form.4x3y7Answer:
Identify Perfect Squares: Identify the perfect squares within the radicand. The radicand is 4x3y7. We can see that 4 is a perfect square, x3 contains a perfect square (x2), and y7 contains a perfect square (y6).
Rewrite Radicand: Rewrite the radicand by separating the perfect squares from the non-perfect squares. 4x3y7=4×x2×x×y6×y
Take Square Roots: Take the square root of the perfect squares and leave the non-perfect squares inside the radical. 4×x2×y6×x×y = 2×x×y3×x×y
Combine Square Roots: Combine the square roots of the non-perfect squares. 2×x×y3×xy
Write Final Expression: Write the final expression in simplest radical form.The simplest radical form of the expression is 2xy3xy.
