9^3x+1 - 5(9^x) = 108
the answer is said to be 1/2. But i can't seem to get it and i
think the question is wrong somehow. Please help. and there's
another one.
square 5 / square root 25 = 1/125
It says to solve the equation. May I ask what the question is
looking for really? There doesn't seem to be an unknown.Thanks.
