Given:

If √((a))b = a2 + 5b

Formula used:

√((a))b = a2 + 5b

Calculations:

We will solve this question using the options.

Option 1): When, a = 3 and b = 4

Putting the values in \(√{(a)^b}=a^2+5b\), we get

√(3)4 ≠ (32 + 5×4)

9 ≠ 29. So, Option 1) is not correct.

Option 2): When a = 4 and b = 18

√(4)18 ≠ (16 + 90)

262144 ≠ 106. So, Option 2) is not correct.

Option 3): When a = 2 and b = 12

√(2)12 = (4 + 60)

64 = 64. So, Option 3) is correct.

∴ The correct answer is Option 3).
