Answer:
3^-2 = 1/3^2 = 1/9
Step-by-step explanation:
3^4 * 3^-6
Using the properties of exponents
We know that a^b * a^c = a^(b+c)
3^4 * 3^-6 = 3^-2
If we only want positive exponents
We know that a^-b = 1/a^b
3^-2 = 1/3^2 = 1/9
We can also look at it
The negative exponent puts the 3's in the denominator
3*3*3*3 * 1/ (3*3*3*3*3*3)
Canceling
1/ (3*3)
1/9
