WEI KIT RETURNS! Homework Help ✎

Wei Kit sure loves exponents! He’s decided to rewrite all the numbers around him so that they have an exponent. For example, instead of writing the number 2, he writes:

He insists he can also write the number 2 as

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

One way:

Find another way.Simplify this expression:

Refer to previous hints.
