Answer:
We can say that \((-1)^x\) is positive, when x is even positive number.
Step-by-step explanation:
A negative number raised to an even power will always produce a positive result.
Like \((-1)^{2} =1\)
\((-1)^{4} =1\)
\((-1)^{10} =1\)
We can say that \((-1)^x\) is positive, when x is even positive number.
