Example

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

Question

$$\left. \begin{array} { l } { - 1.46666667 - } \\ { \frac { b - c } { 3 c + 4 b } \div \frac { b c } { a } + \frac { a c } { b } } \end{array} \right.$$

Answer

$$-1-466666667*a*n*sindecimalb-c^2/b+a*c;3*c+4*b^2*a$$

Solution


Move the negative sign to the left.
\[\begin{aligned}&-1-466666667ansindecimalb-\frac{c}{b}c+ac\\&3c+4bab\end{aligned}\]
Use this rule: \(\frac{a}{b} \times c=\frac{ac}{b}\).
\[\begin{aligned}&-1-466666667ansindecimalb-\frac{cc}{b}+ac\\&3c+4bab\end{aligned}\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[\begin{aligned}&-1-466666667ansindecimalb-\frac{{c}^{2}}{b}+ac\\&3c+4bab\end{aligned}\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[\begin{aligned}&-1-466666667ansindecimalb-\frac{{c}^{2}}{b}+ac\\&3c+4{b}^{2}a\end{aligned}\]
