Answer: 
Step-by-step explanation: Given expression
.
The first factor
has a degree of : 2 because power of a is 2.
The second factor
has a degree of : 3 because power of a is 3.
The third factor
has a degree of : 2 because highest power of a is 2.
Let us multiply them now:

First we would multiply
.
According to product rule of exponents, we would add the powers of a.
Therefore,

Now, we need to distribute
over 
Therefore,

=
Highest power of resulting polynomial
is 7.
Therefore, The product has a degree of 7.
4.509 is greater that 4.508 and less than 4.512
Its not possible because if you try to multiply back and forth it wont work.
