Math Problem Statement

Solve; (5-2)³×2+[-4+(-7)÷(-2+4)²

Solution

Let's solve the expression step by step:

Given expression:
(52)3×2+[4+7(2+4)2](5-2)^3 \times 2 + \left[-4 + \frac{-7}{(-2+4)^2}\right]

Step 1: Simplify the parentheses and exponents

  1. 52=35 - 2 = 3
  2. 33=273^3 = 27
  3. 2+4=2-2 + 4 = 2
  4. 22=42^2 = 4

Step 2: Substitute back and simplify further

Now substitute these results back into the expression: 27×2+[4+74]27 \times 2 + \left[-4 + \frac{-7}{4}\right]

Step 3: Perform the multiplication

54+[4+74]54 + \left[-4 + \frac{-7}{4}\right]

Step 4: Simplify the fraction

74=74=1.75\frac{-7}{4} = -\frac{7}{4} = -1.75

Step 5: Add the terms inside the brackets

41.75=5.75-4 - 1.75 = -5.75

Step 6: Final addition

54+(5.75)=545.75=48.2554 + (-5.75) = 54 - 5.75 = 48.25

Final Answer

48.25\boxed{48.25}
