3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$\left. \begin{array} { l } { ( 7 ) ^ { 3 } + ( 4 ) ^ { 3 } } \\ { = ? } \end{array} \right.$$

Answer

o=407/f

Solution


Simplify  \({7}^{3}\)  to  \(343\).
\[343+{4}^{3}=of\]
Simplify  \({4}^{3}\)  to  \(64\).
\[343+64=of\]
Simplify  \(343+64\)  to  \(407\).
\[407=of\]
Divide both sides by \(f\).
\[\frac{407}{f}=o\]
Switch sides.
\[o=\frac{407}{f}\]
