Question

$$\sqrt { \frac { ( 216 ) ^ { \frac { 2 } { 3 } \times ( 25 ) ^ { \frac { 1 } { 2 } } } { ( .04 ) ^ { \frac { - 1 } { 2 } } } } }$$

Answer

6*Si*IM*m*p*l*f*y

Solution


Rewrite \(216\) as \({6}^{3}\).
\[Simpl\imath fy\sqrt{\frac{{({6}^{3})}^{\frac{2}{3}}\times {25}^{\frac{1}{2}}}{{0.04}^{-\frac{1}{2}}}}\]
Use this rule: \({({x}^{a})}^{b}={x}^{ab}\).
\[Simpl\imath fy\sqrt{\frac{{6}^{\frac{3\times 2}{3}}\times {25}^{\frac{1}{2}}}{{0.04}^{-\frac{1}{2}}}}\]
Simplify  \(3\times 2\)  to  \(6\).
\[Simpl\imath fy\sqrt{\frac{{6}^{\frac{6}{3}}\times {25}^{\frac{1}{2}}}{{0.04}^{-\frac{1}{2}}}}\]
Simplify  \(\frac{6}{3}\)  to  \(2\).
\[Simpl\imath fy\sqrt{\frac{{6}^{2}\times {25}^{\frac{1}{2}}}{{0.04}^{-\frac{1}{2}}}}\]
Simplify  \({6}^{2}\)  to  \(36\).
\[Simpl\imath fy\sqrt{\frac{36\times {25}^{\frac{1}{2}}}{{0.04}^{-\frac{1}{2}}}}\]
Convert \({25}^{\frac{1}{2}}\) to square root.
\[Simpl\imath fy\sqrt{\frac{36\sqrt{25}}{{0.04}^{-\frac{1}{2}}}}\]
Since \(5\times 5=25\), the square root of \(25\) is \(5\).
\[Simpl\imath fy\sqrt{\frac{36\times 5}{{0.04}^{-\frac{1}{2}}}}\]
Simplify  \(36\times 5\)  to  \(180\).
\[Simpl\imath fy\sqrt{\frac{180}{{0.04}^{-\frac{1}{2}}}}\]
Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[Simpl\imath fy\sqrt{\frac{180}{\frac{1}{\sqrt{0.04}}}}\]
Simplify  \(\sqrt{0.04}\)  to  \(0.2\).
\[Simpl\imath fy\sqrt{\frac{180}{\frac{1}{0.2}}}\]
Simplify  \(\frac{1}{0.2}\)  to  \(5\).
\[Simpl\imath fy\sqrt{\frac{180}{5}}\]
Simplify  \(\frac{180}{5}\)  to  \(36\).
\[Simpl\imath fy\sqrt{36}\]
Since \(6\times 6=36\), the square root of \(36\) is \(6\).
\[Simpl\imath fy\times 6\]
Regroup terms.
\[6Si\imath mplfy\]
