Answer:
1 in 7
Step-by-step explanation:
Your one-digit choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
But they're nonzero, so: 1, 2, 3, 4, 5, 6, 7, 8, 9.
But they can't be repeated and 9 and 8 are used, so: 1, 2, 3, 4, 5, 6, 7.
Only 7 numbers left, so chances are, 1 in 7.
both because thats what i think
x= k/a-b
Move all terms to the left side and set equal to zero as well as each factor.
Hope this helps.

log(x) is the inverse function of an exponent. "log base 8 of xyz" means "what number do I have to raise 8 to, to get xyz". In this case, it means, "what number do I have to raise 8 to, to get x + 1". That's simple, it's just x + 1!
