Answer

$2x^2\sqrt{6x}$

Work Step by Step

Simplify. $\sqrt{6x^3}\sqrt{4x^2}$ As per definition of square root property,we have $(p)^{\frac{m}{n}}=(\sqrt[n] {p})^m$ Thus, the given radical term can be written as: $\sqrt{6x^3}\sqrt{4x^2}=\sqrt{(6x^3)(4x^2)}$ Since, the power raised to a same exponent or base gets add when they are in multiply form. or,$=\sqrt{24x^{3+2}}$ or, $=\sqrt{24x^{5}}$ or, $=\sqrt{4x^{4}}\sqrt{6x}$ or,$=\sqrt{(2x^2)^2}\sqrt{6x}$ Hence, the above exponent in radical form can be written as: $2x^2\sqrt{6x}$
