This is really like saying:
-y5 * -y5 * -y5 * -y5
When you multiply a even number of negative numbers the result is POSITIVE. So we have:
y5*y5*y5*y5
Since the base of each exponent is the same (y), you can just add the exponents in this case and get:
y (5+5+5+5) or y20 ( that is, "y to the 20th power")
