Answer:
3f+8g
Step-by-step explanation:
It is different because to find out the answer, change all denominators to 10, since the LCD is 10.
6/10-5/10=1/10
6/10-6/10=0/10
1/10 is not equal to 0/10
Top= 198
bottom= 9
108/6=18
18= constant porportional (think thats what its called)
162/18=9
11x18=198
Answer:
y= 1/4,1/2,1,2,4,8,16,32,64
Step-by-step explanation:
Make negative powers positive by turning them into a fraction so 
is really
= 
so 
is just 
. then 
=1 [any number to the zero power is = 1],
2^1 = 2, 2^2=4, 2^3=8, 2^4=16, 2^5=32, 2^6 = 2x2x2x2x2x2=64
