Answer 1

b

Explanation:

Answer 2

The answer is option B

Explanation:

`{3}^(5) . {3}^(4)`

To solve this question we use the rules of indices.

That's since the bases are the same and are multiplying we add the exponents

That's

`{a}^(x) . {a}^(y) = {a}^(x + y)`

So from the question

`{3}^(5) . {3}^(4) = {3}^(5 + 4)`

We have the final answer as

`{3}^(9)`

Hope this helps you
