He insists he can also write the number 2 as  and !

  1. Explain why Wei Kit’s expressions all equal 2.

    Consider: 

    First consider just the exponent: It can be translated as '3 to the power of something that makes 3 become x.'
    Now consider the entire expression: 3 is being raised to that 'something' that makes 3 become x...
    Consequently, the expression = x.

  2. Use Wei Kit’s method to rewrite the number 9 in two different ways.

    One way: 
    Find another way.

  3. Simplify this expression:

    Refer to previous hints.

  4. How can Wei Kit rewrite so that it has a base of 7?

    One way: 7 = 7??????
