Simplify Completely. Make sure the domain and range of the simplified version match the domain and range of the original:
\( \displaystyle x \sqrt[5]{4x} \)
\( \displaystyle 3x^2 \sqrt{21x} \)
\( \displaystyle \frac{1}{9} \)
\( \displaystyle \sqrt{6} \)
\( \displaystyle -\sqrt{10} - \sqrt{15} \)
\( \displaystyle \frac{5\sqrt{x + y} + x + y}{25 - x - y} \)
\( \displaystyle \frac{\sqrt[4]{280a}}{10a} \)
\( \displaystyle -14\sqrt{3x} + 75 \sqrt{x} \)
For each of the following, evaluate or identify as undefined:
\( \displaystyle -3\sqrt[3]{2} \)
16
undefined
\( \displaystyle \frac{\sqrt{2}}{4} \)
Simplify completely. Where appropriate, make sure the domain and range of the simplified version is the same as the original.
\( \displaystyle 5\sqrt{2}+ 2x\sqrt{2} + 9|x|\sqrt{2} \)
\( \displaystyle 2xy\sqrt[3]{2y^2} \)
\( \displaystyle \frac{2 \left| x \right| y^2 \sqrt[4]{yz^3}}{\left| z \right|} \) where \( y\) and \(z\) have the same sign.
\( \displaystyle 12\sqrt{2} \)
\( \displaystyle 9ab^3\sqrt{ab} \) where \( a\) and \(b \) have the same sign.
\( \displaystyle \frac{4x^2\sqrt[3]{y}}{y^2} \)
\( \displaystyle \sqrt{3} - 1 \)
\( \displaystyle 49-12\sqrt{5} \)
\( \displaystyle \frac{\left( 5 \sqrt{3} + 6\sqrt{10}\right)}{10} \)
\( \displaystyle \frac{2 \sqrt{xy}}{xy} \)
\( \displaystyle xy^2 \sqrt[3]{2xy} \)
\( \displaystyle \frac{\sqrt{2}}{2} \)
Solve the following:
\( \displaystyle \{ 3 \} \)
\( \displaystyle \{ 6 \} \)
