Answer:

  z^11

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)(a^c) = a^(b+c)

__

  z^5\cdot z^6=z^{5+6}=\boxed{z^{11}}

__

<em>Additional comment</em>

It might help you to think of an exponent as indicating repeated multiplication. It tells you how many times the factor is repeated. In this case, it means ...

  z^5\cdot z^6=(z\cdot z\cdot z\cdot z\cdot z)\cdot(z\cdot z\cdot z\cdot z\cdot z\cdot z)\\=z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z = z^{11}

How can I remember the special right triangle formulas?

Also, you can print out worksheets and make your brain remember. PRACTICE!
