Question

ScanSolve AI Tutor · Accepted Answer

Step 1: Evaluate the expression under the vinculum (the bar over 13−3). 13−3 = 10 Step 2: Substitute this value back into the expression and evaluate the innermost parenthesis. 55 − 10 = 45 Step 3: Substitute this value back into the expression and perform the multiplication inside the square brackets. 20 × 45 = 900 Step 4: Perform the division inside the square brackets. 900 ÷ (−5) = −180 Step 5: Perform the subtraction inside the square brackets. 8 − (−180) = 8 + 180 = 188 Step 6: Multiply the result of the square brackets by 1/5. 1/5 × 188 = 188/5 = 37.6 Step 7: Perform the final addition. 19 + 37.6 = 56.6 The final answer is 56.6.
