Answer:
4.0800*10^4
Step-by-step explanation:
4.9*10^4=49000
49000-8200=40800
since we can only have base numbers 1-9 in scientific notation, we need to move the decimal left 4 places:

Answer:
2
Step-by-step explanation:
median is the number at the center
1,(2),8
Here is an example(i don't really know how to explain)
4n-2n+4=-1+17
2n+4=-1+17
-1+17=16
2n+4=16
Move + 4 to the other side. Sign changes from +4 to -4
2n+4-4=16-4
2n=12
Divide by 2 for 2n and 12
2n/2=12/2
n=6
Check answer by using substitution method
4(6)-2(6)+4=16
24-12+4=16
12+4=16
16=16
Answer : n=6
