If -5n - 125- then 5n-64 - 6251-5251-125

The correct option is C 25 √(5^n) = 125, 5^n/2= 5^3 Comparing, we get n/2 = 3 ⇒ n = 6 Now 5^n√(64)= 5^64^1/n = 5^64^1/6 = 5^(2^6)^1/6 = 5^2^6 ×1/6 = 5^2 = ...

Solution

The correct option is A
25

$\sqrt{5^{n}} = 125, 5^{\frac{n}{2}} = 5^{3} C o m p a r i n g, w e g e t \frac{n}{2} = 3 \Rightarrow n = 6 N o w 5^{n \sqrt{64}} = 5^{64^{\frac{1}{n}}} = 5^{64^{\frac{1}{6}}} = 5^{(2^{6})^{\frac{1}{6}}} = 5^{2^{6 \times \frac{1}{6}}} = 5^{2} = 25$
