5=a^x ⇒a=5^(1/x)   (5/a)=(a^x /a)=a^(x−1) =(5^(1/x) )^(x−1) =5^((x−1)/x)   (5/a)=(5/5^(1/x) )=5^(1−1/x) =5^((x−1)/x)
$$\mathrm{5}={a}^{{x}} \Rightarrow{a}=\mathrm{5}^{\mathrm{1}/{x}} \\ $$$$\frac{\mathrm{5}}{{a}}=\frac{{a}^{{x}} }{{a}}={a}^{{x}−\mathrm{1}} =\left(\mathrm{5}^{\mathrm{1}/{x}} \right)^{{x}−\mathrm{1}} =\mathrm{5}^{\frac{{x}−\mathrm{1}}{{x}}} \\ $$$$\frac{\mathrm{5}}{{a}}=\frac{\mathrm{5}}{\mathrm{5}^{\mathrm{1}/{x}} }=\mathrm{5}^{\mathrm{1}−\mathrm{1}/{x}} =\mathrm{5}^{\frac{{x}−\mathrm{1}}{{x}}} \\ $$
