Question

$$\left. \begin{array} { l } { 7 \sqrt { 8 } \times \frac { 2 } { 7 \sqrt { 2 } } = } \end{array} \right.$$

Answer

A=(Wo*r*k*IM*n*g*o*u*t)/1.5428571428571

Solution


Simplify  \(\sqrt{8}\)  to  \(2\sqrt{2}\).
\[A\times 2.7\times 2\sqrt{2}\times \frac{2}{7\sqrt{2}}=Work\imath ngout\]
Cancel \(\sqrt{2}\).
\[A\times 2.7\times 2\times \frac{2}{7}=Work\imath ngout\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{A\times 2.7\times 2\times 2}{7}=Work\imath ngout\]
Simplify  \(A\times 2.7\times 2\times 2\)  to  \((10.8)A\).
\[\frac{10.8A}{7}=Work\imath ngout\]
Simplify  \(\frac{10.8A}{7}\)  to  \(1.542857A\).
\[1.542857A=Work\imath ngout\]
Divide both sides by \(1.542857\).
\[A=\frac{Work\imath ngout}{1.542857}\]
