Breakdown into Prime Factors: First, let's break down 28 into its prime factors.28=2×2×7
Group Identical Factors: Now, we group the identical factors and use the exponent rule. 328=322×7
Apply Product Property: Next, we apply the product property of radicals to separate the square root of the perfect square from the rest.322×7=3×22×7
Simplify by Cancelling Squares: Since the square root and the square cancel each other out, we simplify. 3×22×7=3×2×7
Multiply Numbers Outside: Finally, we multiply the numbers outside the square root. 3×2×7=67
