Q. Simplify. Assume x is greater than or equal to zero.75x9
Factorization: Factor 75x9 into its prime factors and perfect squares.75 can be factored into 3×5×5, and x9 is (x4)2×x. So, we have:75x9=3×52×(x4)2×x
Separation: Separate the perfect squares from the non-perfect squares inside the radical.We can rewrite the expression as:52⋅(x4)2⋅3x
Square Roots: Take the square root of the perfect squares.The square root of 52 is 5, and the square root of (x4)2 is x4. We then have:5×x4×3x
Final Expression: Write the final simplified expression.The simplified form of the original expression is:5x4⋅3x
