Answer:
b] 4
Step-by-step explanation:
27^k = 3^3k
On transposing 3^k to LHS:
3^3k . 3^k = 9
⇒ 3 ^4k = 3^2 [9 = 3 x 3 = 3^2]
On comparing the powers of 3
4k = 2
⇒ k = 1/2
Therefore 1/k² = {1/k}² [Because 1² = 1]
= [2]²

Answer:
your answer is (b) 4.
Step-by-step explanation:
(3^3)^k = (3^2) ÷ (3^k).
so, base is same than,
(3)^3k= (3^2-k).
comparing the power of both side.
3k= 2-k
4k = 2.
k= 1/2.
so , 1/(k^2) = 4( ans)
