Answer:

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)(a^c) = a^(b+c)

You have ...

(x^3)(x^a) = x^17

x^(3+a) = x^17

Equating exponents, we get ...

3 +a = 17

a = 14

The missing exponent is 14.

The reciprocal of a fraction $\frac{a}{b}$ is the same fraction "upside down" $\frac{b}{a}$ .

The reciprocal of a whole number $N$ is "1 over" that number $\frac{1}{N}$ .
