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

Answer:
Only Annabelle is correct.
Step-by-step explanation:
So we have the expression:
[tex](4^27^5)(4^37^2)[/tex]
When multiplying exponents with the same base, we can use the following property:
[tex]x^ax^b=x^{a+b}[/tex]
Essentially, we add the exponents together.
So, first group them:
[tex]=(4^24^3)(7^57^2)[/tex]
Use the property:
[tex]=4^{2+3}7^{5+2}[/tex]
And so our answer is:
[tex]=4^57^7[/tex]
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!
