If \(\sqrt{3^n}\) = 81. Then, n is equal to (a) 2 (b) 4 (c) 6 (d

1.	If \(\sqrt{3^n}\) = 81. Then, n is equal to (a) 2 (b) 4 (c) 6 (d) 8
Answer» (d) 8 \(\sqrt{3^n}\) = 81 ⇒ 3^n/2 = 3⁴ ⇒ \(\frac{n}2\) = 4 ⇒ n = 8

If \(\sqrt{3^n}\) = 81. Then, n is equal to (a) 2 (b) 4 (c) 6 (d) 8

Answer»

(d) 8

\(\sqrt{3^n}\) = 81 ⇒ 3^n/2 = 3⁴ ⇒ \(\frac{n}2\) = 4 ⇒ n = 8
