If a ∗ ∗ b = + √ab a b , evaluate 2 ∗ ∗ (12 ∗ ∗ 27)

If a $\ast$ b = + $\sqrt{ab}$, evaluate 2 $\ast$(12 $\ast$ 27)

Answer Details

We can start by evaluating 12 ∗ ∗  27 using the given formula: 12 ∗ ∗  27 = + √(12 x 27) = + √(324) = 18 Then we can substitute this value in 2 ∗ ∗ (12 ∗ ∗  27) as follows: 2 ∗ ∗ (12 ∗ ∗  27) = 2 ∗ ∗ (18) = + √(2 x 18) = + √36 = +6 or -6 Therefore, the answer is either 6 or -6, depending on whether the sign is positive or negative, which is not specified in the question.
