Question

Write 5^-15 with a positive exponent

Answer 1

Given:

`5^(-15)`

To change a negative exponent to a positive exponent, the variable will change from numerator to denominator and vice versa.

For example:

`\begin{gathered} P^(-1)\text{ = }(1)/(P) \\ \\ We\text{ know that:} \\ 5^(-15)=5^((15)-1) \\ \\ 5^((15)-1)\text{ = }(1)/(5^(15)) \end{gathered}`

Therefore, we have:

`5^(-15)\text{ = }(1)/(5^(15))`

ANSWER:

`(1)/(5^(15))`
