Q. Simplify. Assume f is greater than or equal to zero.12f7
Factor and Express:12f7First, we need to factor the radicand (the number inside the square root) into its prime factors and express the variable f in a way that will allow us to simplify the square root.12f7=2×2×3×f7
Group and Simplify:2×2×3×f7 Now, we group the identical factors and express f7 as f6×f to make use of the even exponent. 2×2×3×f6×f=22×3×f6×f
Apply Product Property:22×3×f6×fWe apply the product property of radicals, which allows us to take the square root of each factor separately.22×3×f6×f=22×3×f6×f
Simplify Perfect Squares:12f7=22⋅3⋅f6⋅f We simplify the square roots of the perfect squares, which are 22 and f6. 22⋅3⋅f6⋅f=2⋅3⋅f3⋅f
Final Simplification: Final SimplificationCombine the constants and the variables outside the square root to get the final simplified form.2⋅f3⋅3⋅f=2f3⋅3f
