79.90*0.8= 63.92
Answer
63.92
For this case we must algebraically rewrite the given expression. So:
x: It is the variable that represents an unknown number
"double a number" is represented as: 
"6 less than double a number" is represented as: 
So, the final expression is: 
If we want to rewrite the expression in an equivalent way, we take common factor 2:

Asnwer:

Equivalent expression: 
Answer:
The only positive integers would be anything less than 3. So 1 or 2 would work
Step-by-step explanation:
If something that is already being raised to a power, gets raised to another power, those powers add up. So if it were
, the exponents would add which would make it
.
In the case of your question, if 'n' was 2 it would be to the power of 6 making it less than to the power of. 1 could also work
