What is the expression in simplest radical form?
Sqrt 432
My answer--> 12 Sqrt 3
Am I right?
Simplify. ^3 Sqrt125x^21y^33
My answer--> 5x^10y^16 Sqrt5xy
Am I right?
Simplify. 9 Sqrt56x^7y^12
My answer--> 18x^3y^6 Sqrt14x
Am I right?
+9466 \(\sqrt{432}\,=\,\sqrt{2*2*2*2*3*3*3}\,=\,\sqrt{2*2}*\sqrt{2*2}*\sqrt{3*3}*\sqrt3\,=\,2*2*3*\sqrt3\)
\(=\,12\sqrt3\) Right!
Is this the third one??
\(\sqrt[3]{125x^{21}y^{33}}\,\,=\,(125x^{21}y^{33})^{\frac13}\,=\,125^{\frac13}x^{\frac{21}{3}}y^{\frac{33}{3}}\,=\,5x^{7}y^{11}\)
\(9\sqrt{56x^7y^{12}}\,=\,9\sqrt{2*2*2*7*x*x^6*y^{12}}\,=\,9*\sqrt{2*2}*\sqrt{2*7*x}*\sqrt{x^6}*\sqrt{y^{12}}\\~\\=\,9*2*\sqrt{14x}*x^3*y^6\,=\,18x^3y^6\sqrt{14x}\)
