Answer:
30064, if round trip multiply by 2
Step-by-step explanation:
so this is just multiplication. I am not sure if its round trip, but if its not then its just the 7516 times 4= 30064
7x7(12+9) to the power of 3
F is odd if and only f f(-x) = -f(x) so f(x) = 0 works because 0 = 0 always.
f is even if and only if f(-x) = f(x) so f(x) = 0 works because there's no x term so nothing changes. 0 = 0.
