Answer
The simplified form is \( 180\sqrt{3} \times x^{2} \).
Solution
Calculate or simplify the expression \( (5x\sqrt{18x})(6\sqrt{6x}) \).
Simplify the expression by following steps:
- step0: Solution:
\(\left(5x\sqrt{18x}\right)\left(6\sqrt{6x}\right)\)
- step1: Remove the parentheses:
\(5x\sqrt{18x}\times 6\sqrt{6x}\)
- step2: Simplify the root:
\(5x\times 3\sqrt{2x}\times 6\sqrt{6x}\)
- step3: Multiply the terms:
\(90x\sqrt{2x}\times \sqrt{6x}\)
- step4: Multiply the terms:
\(90x\times 2\sqrt{3}\times x\)
- step5: Multiply the terms:
\(180\sqrt{3}\times x\times x\)
- step6: Multiply the terms:
\(180\sqrt{3}\times x^{2}\)
The simplified form of the expression \( (5x\sqrt{18x})(6\sqrt{6x}) \) is \( 180\sqrt{3} \times x^{2} \).

Beyond the Answer
To simplify \( (5 x \sqrt{18 x})(6 \sqrt{6 x}) \), first multiply the coefficients: \( 5 \times 6 = 30 \). Next, simplify the radicals: \( \sqrt{18 x} = \sqrt{18} \cdot \sqrt{x} = 3\sqrt{2} \cdot \sqrt{x} \) and \( \sqrt{6 x} = \sqrt{6} \cdot \sqrt{x} \). So now we have: \[ (30x)(3 \sqrt{2} \sqrt{x})(\sqrt{6} \sqrt{x}) = 30x \cdot 3 \sqrt{12} \cdot x = 90x \cdot 2\sqrt{3} \cdot x \] Combine the terms to get \( 180x^2 \sqrt{3} \). The simplified form is \( 180x^2 \sqrt{3} \).
