Answer: -i

Step-by-step explanation:

You need to remember:

1. The Product of powers property: (a^m)(a^n)=a^{(m+n)}

2. The Power of a power property: (a^m)^n=a^{mn}

In this case, given:

i^{15}

You need to follow these steps in order to simplify it:

1. Apply the Product of powers property:

i^{15}=i^{12}i^2i

2. Apply the Power of a power property:

(i^{4})^3i^2i

3. Finally, since i^4=1 and i^2=-1, you get:

 =(1)(-1)(i)=-i
