Answer 1

Logarithms are the inverse of exponents.

If a = logb(c), then c = b ^ a (where ^ indicates, exponentiation, not XOR).

Answer 2

The base 10 antilog is just 10^x (that is, 10 raised to the *x*th power). As the link below says, the "antilog" notation is still used, but not very often. Is there a reason the normal exponential notation doesn't work for you?

Answer 3

antilog? you mean power?

try

<msup>
  <mi>10</mi>
  <mn>x</mn>
</msup>
