Answer 1

`5^(9)` can not be expressed as a square of any other number.

Step-by-step explanation:

The number 1953125 is equal to
`5^(9)`.

Now, the above statement gives an idea that 1953125 i.e.
`5^(9)` is not a square number as 9 is not a multiple of 2.

So, we can not express
`5^(9)` as a square of any other number.

We can only express
`5^(9)` as
`(5^(4) )^(2) * 5`.
