Q. Simplify. Assume x is greater than or equal to zero.45x9
Factorization: Factor 45x9 into its prime factors and perfect squares.45 can be factored into 9×5, where 9 is a perfect square. The x9 term can be written as (x4)2×x, where (x4)2 is a perfect square.So, 45x9=9×5×(x4)2×x.
Rewrite Expression: Rewrite the square root of the expression using the factorization. 45x9=9×5×(x4)2×x.
Simplify Square Root: Simplify the square root by taking out the perfect squares. 9×5×(x4)2×x=9×(x4)2×5x. This simplifies to 3×x4×5x.
Combine Terms: Combine the simplified terms outside of the square root. The final simplified expression is 3x4⋅5x.
