Question

$$\sqrt{ \frac{ { 216 }^{ \frac{ 2 }{ 3 } } { \times }^{ { 125 }^{ \frac{ 2 }{ 2 } } } }{ { 0.04 }^{ \frac{ -3 }{ 2 } } } }$$

Answer

$$6*^63*0.04^(3/4)$$

Solution


Cancel \(2\).
\[\sqrt{\frac{{216}^{\frac{2}{3}}{}^{{125}^{1}}}{{0.04}^{\frac{-3}{2}}}}\]
Rewrite \(216\) as \({6}^{3}\).
\[\sqrt{\frac{{({6}^{3})}^{\frac{2}{3}}{}^{{125}^{1}}}{{0.04}^{\frac{-3}{2}}}}\]
Use this rule: \({({x}^{a})}^{b}={x}^{ab}\).
\[\sqrt{\frac{{6}^{\frac{3\times 2}{3}}{}^{{125}^{1}}}{{0.04}^{\frac{-3}{2}}}}\]
Simplify  \(3\times 2\)  to  \(6\).
\[\sqrt{\frac{{6}^{\frac{6}{3}}{}^{{125}^{1}}}{{0.04}^{\frac{-3}{2}}}}\]
Simplify  \(\frac{6}{3}\)  to  \(2\).
\[\sqrt{\frac{{6}^{2}{}^{{125}^{1}}}{{0.04}^{\frac{-3}{2}}}}\]
Simplify  \({6}^{2}\)  to  \(36\).
\[\sqrt{\frac{36{}^{{125}^{1}}}{{0.04}^{\frac{-3}{2}}}}\]
Use Rule of One: \({x}^{1}=x\).
\[\sqrt{\frac{36{}^{125}}{{0.04}^{\frac{-3}{2}}}}\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[\sqrt{\frac{36{}^{126}}{{0.04}^{\frac{-3}{2}}}}\]
Move the negative sign to the left.
\[\sqrt{\frac{36{}^{126}}{{0.04}^{-\frac{3}{2}}}}\]
Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[\sqrt{\frac{36{}^{126}}{\frac{1}{{0.04}^{\frac{3}{2}}}}}\]
Invert and multiply.
\[\sqrt{36{}^{126}\times {0.04}^{\frac{3}{2}}}\]
Use this rule: \(\sqrt{ab}=\sqrt{a}\sqrt{b}\).
\[\sqrt{36}\sqrt{{}^{126}}\sqrt{{0.04}^{\frac{3}{2}}}\]
Since \(6\times 6=36\), the square root of \(36\) is \(6\).
\[6\sqrt{{}^{126}}\sqrt{{0.04}^{\frac{3}{2}}}\]
Simplify  \(\sqrt{{}^{126}}\)  to  \({}^{63}\).
\[6{}^{63}\sqrt{{0.04}^{\frac{3}{2}}}\]
Use this rule: \({({x}^{a})}^{b}={x}^{ab}\).
\[6{}^{63}\times {0.04}^{\frac{3\times 1}{2\times 2}}\]
Simplify  \(3\times 1\)  to  \(3\).
\[6{}^{63}\times {0.04}^{\frac{3}{2\times 2}}\]
Simplify  \(2\times 2\)  to  \(4\).
\[6{}^{63}\times {0.04}^{\frac{3}{4}}\]
