Question

Which expression shows how to write.. (please help me with this!!)

Answer 1

The second one because your doing 3^4 twice

Answer 2

`3^4*3^4`

Explanation:

Well the simple definition of an exponent is:
`x^c=x*x*x*x...\text{ c amount of times}`

So when we have:
`(3^4)^2`

This just means: 3^4, times it self, 2 times.

This can be expressed as:
`3^4*3^4`
