  1. 5^x = 5 to the x power. If so, none of these fit.

    Online "^" is used to indicate an exponent, e.g., x^2 = x squared.

    Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.

    Rewrite your formula in more standard terms.

  2. And, write out the entire problem. One cannot have a solution without an equals sign somewhere.

  3. Why did you re-post the question after it has been answered???
