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

11x-4
Answer:
C
Step-by-step explanation:
x²+2x-15 = x²-3x+5x-15 = x(x-3)+5(x-3)=(x+5)(x-3)
or delta:
∆=2²-4*1*(-15)=4+60=64
√∆=8
x1 = (-2+8)/2 = 3
x2=(-2-8)/2=-5
and 4x+20 = 4(x+5)
The same is (x+5), so it is GCF. answer C
