Solve {r}{3A}{+58/B2}

$$\left. \begin{array} { r } { 3 A } \\ { + \frac { 58 } { B 2 } } \end{array} \right.$$

Evaluate

$$3A+\frac{58}{B_{2}}$$

Solution Steps

To add or subtract expressions, expand them to make their denominators the same. Multiply 3A times \frac{B_{2}}{B_{2}}.

$$\frac{3AB_{2}}{B_{2}}+\frac{58}{B_{2}}$$

Since \frac{3AB_{2}}{B_{2}} and \frac{58}{B_{2}} have the same denominator, add them by adding their numerators.

$$\frac{3AB_{2}+58}{B_{2}}$$

Differentiate w.r.t. A

$$3$$
