Explanation

Let's evaluate each part of the expression step-by-step. Calculate 0.81 : ​ 0.81 = 0.9 ​ Calculate 0.0144 : ​ 0.0144 = 0.12 ​ Calculate 0.4 0.5 :​ 0.4 0.5 ​ = 0.8 Evaluate the inner expression 0.0144 + 0.4 ​ 0.5 : ​ 0.12 + 0.8 = 0.92 Subtract from 0.81 :​ 0.9 − 0.92 = −0.02 Add 0.6 to the result: 0.6 + (−0.02) = 0.58 Answer: The value of the expression is 0.58.
