#1," "a ne 0#

Explanation:

Recall the following rule of exponents:

#x^color(red)a * x^color(blue)b = x^(color(red)a + color(blue)b)#

In this case, we have:

#a^color(red)2 * a^color(blue)(-3) * a^color(orange)1 = a^(color(red)2 + color(blue)((-3)) + color(orange)1) = a^(2-3+1) = a^0 = 1#

This is true as long as #a ne 0#, since that would make the expression #0^0#, which is undefined.
