Question

How do you write `5*5^-5` using only positive exponents?

Answer 1

`1/5^4`

Explanation:

`5 cdot 5^-5`

According to indices `a xx a = a^(1 + 1) = a^2`

We are going to apply that here..

`5^1 cdot 5^-5`

`5^(1 - 5)`

`5^-4`

`1/5^4 -> "Positive Exponent"`

`1/625`

Only positive exponent?

It can't be positive exponent cause it contains a negative exponent in the given question..

To make it a positive exponent is when the positive exponent value is greater than the negative exponent value..

The only positive exponent there is `rArr 1/5^4` which has a positive exponent of `4`
