((19^2-5) *3 / ((19+ 3/19 ) * 19 * (2 - 4)2/3 )) + 3

Let's solve the expression step by step: Calculate the values inside parentheses first: (19^2 - 5) = (361 - 5) = 356 (2 - 4)^(2/3) = (-2)^(2/3) = -1.5874 (cube root of -2) Now, we'll substitute these values back into the expression: (356 * 3) / ((19 + 3/19) * 19 * (-1.5874)) + 3 Calculate the values inside the innermost set of parentheses: (19 + 3/19) ≈ 19.15789 Substitute this value back into the expression: (356 * 3) / (19.15789 * 19 * (-1.5874)) + 3 Continue simplifying: (1068) / (-577.81345) + 3 Now, calculate the division: -1.84834 + 3 Finally, add the two values: -1.84834 + 3 ≈ 1.15166 So, the value of the expression is approximately 1.152.
