Answer: 
Step-by-step explanation:
1. To simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.
2. Keeping this property on mind you have, you can rewrite the expression as following and simplify:

1: 8 faces and 9 with the base 9 vertices and 16 edges
2: 3 faces and 5 with the bases 6 vertices and 9 edges
3: 3 faces and 4 with the base 4 vertices and 6 edges
Factor the equation:

set each part of the factorized equation to zero and solve for x the results are your zeros:
x+3 = 0
x = -3x-8 = 0
x = 8
Answer:
Step-by-step explanation:
Well 6 to the second power is when you multiply 6 x 6 = 36
And ab= -320
