Q. Assuming x and y are both positive, write the following expression in simplest radical form.x275x3y6Answer:
Factor and Simplify: First, we will factor the number 75 inside the square root to prime factors to see if any can be taken out of the square root.75=3×25=3×52
Rewrite and Simplify Square Roots: Next, we will rewrite the square root of the product as the product of square roots, and then simplify the square roots of the perfect squares.75x3y6=3×52×x2×x×y6=3×52×x2×x×y6=5×x×y3×3×x
Multiply by x2: Now, we will multiply the simplified square root by x2.x2×(5×x×y3×3×x)=5×x3×y3×3×x
Combine and Simplify: Finally, we will combine the square roots and write the expression in its simplest radical form. 5×x3×y3×3x
