Question

How do you solve `log x=3`?

Answer 1

`x = 1000`

Explanation:

Remember the definition of logarithm, that is
If `log_b(a) = c` is true, then `a = b^c`, and if no base is explicitly put we always assume it's the base 10 (unless it's written as `lnx` in which case the base is the irrational number `e`)

`logx = 3 rarr x = 10^3 rarr x = 1000`
