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

=4

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)
