Simplifying (66x2)(830x4)(6\sqrt{6x^2})(8\sqrt{30x^4}) and (−412y34)(−8y34)(-4\sqrt[4]{12y^3})(-\sqrt[4]{8y^3})

Practice multiplying and simplifying radical expressions with coefficients and variables.

ⓐ (66x2)(830x4)(6\sqrt{6x^2})(8\sqrt{30x^4}): Multiply the coefficients and radicands: (66x2)(830x4)=48180x6(6\sqrt{6x^2})(8\sqrt{30x^4}) = 48\sqrt{180x^6} Extract the largest perfect square factor (36x636x^6): 4836x6⋅5=4836x6⋅548\sqrt{36x^6 \cdot 5} = 48\sqrt{36x^6} \cdot \sqrt{5} Simplify the perfect square and multiply the coefficients: 48⋅6x35=288x3548 \cdot 6x^3\sqrt{5} = 288x^3\sqrt{5}

ⓑ (−412y34)(−8y34)(-4\sqrt[4]{12y^3})(-\sqrt[4]{8y^3}): Multiply the coefficients (−4⋅−1=4-4 \cdot -1 = 4) and radicands: (−412y34)(−8y34)=496y64(-4\sqrt[4]{12y^3})(-\sqrt[4]{8y^3}) = 4\sqrt[4]{96y^6} Extract the largest perfect fourth power factor (16y416y^4): 416y4⋅6y24=416y44⋅6y244\sqrt[4]{16y^4 \cdot 6y^2} = 4\sqrt[4]{16y^4} \cdot \sqrt[4]{6y^2} Simplify and multiply: 4⋅2y6y24=8y6y244 \cdot 2y\sqrt[4]{6y^2} = 8y\sqrt[4]{6y^2}
