Question

Last question! I’m finished after this! Most points I can offer ^^

Answer 1

Only Annabelle is correct.

Explanation:

So we have the expression:

`(4^27^5)(4^37^2)`

When multiplying exponents with the same base, we can use the following property:

`x^ax^b=x^(a+b)`

Essentially, we add the exponents together.

So, first group them:

`=(4^24^3)(7^57^2)`

Use the property:

`=4^(2+3)7^(5+2)`

And so our answer is:

`=4^57^7`

So, Annabelle's answer is correct.

Navene incorrectly used the property. The property adds the exponents, it doesn't multiply them.

So, only Annabelle is correct.

And that's our answer :)

P.S. Congratulations on finishing!
