Q. ( 8/10 )

(10² + 2²)² – 5! – 84 ÷ 2

= (10(10) + 2(2))² – 5(4)(3)(2)(1) – 84 ÷ 2

= (100 + 4)² – 20(3)(2)(1) – 84 ÷ 2

= 104² – 60(2)(1) – 84 ÷ 2

= 104(104) – 120(1) – 84 ÷ 2

= 10.816 – 120 – 84 ÷ 2

= 10.816 – 120 – 42

= 10.816 – 162

= 10.654

🙂

(10² + 2²)² – 5! – 84 : 2

((10 × 10) + (2 × 2))² – (5 × 4 × 3 × 2 × 1) – 84 : 2

(100 + 4)² – (20 × 6) – 42

104² – 120 – 42

10.816 – 120 – 42

10.696 – 42

10.654
