Solve 14cm/x7cm

$$\frac { 14 cm } { x } 7 cm$$

Evaluate

$$\frac{98\left(cm\right)^{2}}{x}$$

Solution Steps

Express \frac{14cm}{x}\times 7 as a single fraction.

$$\frac{14cm\times 7}{x}cm$$

Express \frac{14cm\times 7}{x}c as a single fraction.

$$\frac{14cm\times 7c}{x}m$$

Express \frac{14cm\times 7c}{x}m as a single fraction.

$$\frac{14cm\times 7cm}{x}$$

Multiply c and c to get c^{2}.

$$\frac{14c^{2}m\times 7m}{x}$$

Multiply m and m to get m^{2}.

$$\frac{14c^{2}m^{2}\times 7}{x}$$

Multiply 14 and 7 to get 98.

$$\frac{98c^{2}m^{2}}{x}$$

Differentiate w.r.t. x

$$-98\times \left(\frac{cm}{x}\right)^{2}$$
