Sure, I could walk you through that!  The thing you’re really asking about is just a way to write the same number in more than one way.
assistant
Okay, go on
user
What do you want me to write?  Let’s just pick the number 6 to start with.
assistant
Lets pick the number 100
user
Alright.  You want to express the number 100 using the rules of exponential notation.  What does that mean?
assistant
Well, that's what I am asking you. I am asking you to describe the meaning of exponential notation and we can use the number 100 as an example
user
That's tricky! It's not just the number 100, there are actually lots of numbers and the idea of exponential notation is pretty complicated.  I can probably show you a simple example first, and then I can explain why it's more complicated than it seems.
assistant
Okay, lets see
user
Let’s write down 100 first.  In your handwriting.  So you have one '0', one '1', and one '0', and I have four.  That's where the idea of 'exponents' comes from, it's just a way of writing one number more than another number.  So if I write the number 100 with an 'e' to the right, like this '10e', I mean the number 100 with an 'e' to the right.  Now when you see something like '10e' or '9e', you know it's a number to the power of 'e' - what we call 'exponential notation'.
assistant
So than that would be 10 to the what, if our final number is 100
user
The number '10' has a value of '1', so that means that the exponent of 10 will be a '1', the exponent of 9 will be a '2', the exponent of 8 will be a '3', and so on. So in the number 100, the exponent of 10 will be a '2'.  So the value of 100 in exponential notation will be 10 to the 2nd power - that is, 100.  Are you understanding this so far?
assistant
Yes, 10 the power of 2 is right
