Since (-5)2 using the exponential symbol can be written as (-5)^2
This means -5 in 2 places
(-5)X, using the exponential symbol, can be written as (-5)^X
X(-5), using the exponential symbol can be written as X^(-5)
Therefore:
(-5)X - X(-5) = 17, in exponential form, can be written as:
(-5)^X - X^(-5) = 17
[tex](-5)^X-X^{-5}=\text{ 17}[/tex]
