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

Answer 1

Answer:

Only Annabelle is correct.

Step-by-step 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!
