no
It's impossible. Powers are always either positive or complex.
The solution is: x = 1 and y = -1
x = b/(a + c)
1/a = 1/b: cross multiplying gives a = b
it means that A and B have the same power
15-b=7.
Example: 24 = 42
b = -3
The second equation is not complete and there is not sufficient information for a solution. It would make no sense for me to guess what a + b equals since, in that case, I may as well start posting my own questions and answering them!
a= 2, b = 3 (or vice-versa)
Any number to the power '0' equals '1'. Proof ; Let a^(n) = b Then dividing a^(n) / a^(n) = b/b a^(n-n) = b/b a^(0) = 1
b = 7 (74 = 2,401)
30
2a2b2+3a2b2-5abc
If "and" represents + or *, then the only integer solution is a = 41285 and b = 1 (or the other way around).
8 1/3 = ab^-1, 1.8 =ab^2
