Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that
We have the a² and the b² in the equation 
, and we <em>almost </em>have a 2ab in the equation 
. To get that 2ab, we can simply double both sides of the first equation to get 
. From there, we'll add the first two equations together, giving us the summed equation
And since , we can equivalently say that
Answer: 4
Step-by-step explanation:
( f o g ) (3) means f(g(3)) so...
First: plug 3 into g(x) = x^ (2-1)
3^ (2-1) is 3^1 = 3
Next: plug 3 into f(x)= 2^(x-1)
2^(3-1) is 2^(2) > 2×2 = 4
