a) \( \{25 \div 5+[(77 \div 7 \times 2)-(36 \times 2 \div 8)]+13 \times 3\}= \)

Calculate or simplify the expression \( 25 \div 5+[(77 \div 7 \times 2)-(36 \times 2 \div 8)]+13 \times 3 \). Calculate the value by following steps: - step0: Calculate: \(25\div 5+\left(\left(77\div 7\times 2\right)-\left(36\times 2\div 8\right)\right)+13\times 3\) - step1: Divide the numbers: \(25\div 5+\left(\left(11\times 2\right)-\left(36\times 2\div 8\right)\right)+13\times 3\) - step2: Multiply the numbers: \(25\div 5+\left(22-\left(36\times 2\div 8\right)\right)+13\times 3\) - step3: Multiply the numbers: \(25\div 5+\left(22-\left(72\div 8\right)\right)+13\times 3\) - step4: Divide the numbers: \(25\div 5+\left(22-9\right)+13\times 3\) - step5: Subtract the numbers: \(25\div 5+13+13\times 3\) - step6: Divide the numbers: \(5+13+13\times 3\) - step7: Multiply the numbers: \(5+13+39\) - step8: Add the numbers: \(57\) La expresión \(25 \div 5+[(77 \div 7 \times 2)-(36 \times 2 \div 8)]+13 \times 3\) se simplifica a 57.
