Solve 19c2/20c_{2}

$$\frac { 19 c 2 } { 20 c _ { 2 } }$$

Evaluate

$$\frac{19}{20}=0.95$$

Steps for Quotient of Exponentials

Use the rules of exponents to simplify the expression.

$$\frac{19^{1}c_{2}^{1}}{20^{1}c_{2}^{1}}$$

To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent.

$$\frac{19^{1}c_{2}^{1-1}}{20^{1}}$$

Subtract 1 from 1.

$$\frac{19^{1}c_{2}^{0}}{20^{1}}$$

For any number a except 0, a^{0}=1.

$$\frac{19^{1}}{20^{1}}$$

Divide 19 by 20.

$$\frac{19}{20}$$

Factor

$$\frac{19}{2 ^ {2} \cdot 5} = 0.95$$
