    Now consider the entire expression: is being raised to that 'something' that makes become ...
    Consequently, the expression .

  2. Use Wei Kit's method to rewrite the number in two different ways.

    One way: 
    Find another way.

  3. Simplify this expression:

    Refer to previous hints.

  4. How could Wei Kit rewrite so that it has a base of ?

    One way:
