1) (10² + 11² + 12²) ÷ 73 + 895= (100 + 121 + 144) ÷ 73 + 895= 365 ÷ 73 + 895= 5 + 895= 900
2) 2555 ÷ (13² + 14²) + 35= 2555 ÷ (169 + 196) + 35= 2555 ÷ 365 + 35= 7 + 35= 42
1) (10² + 11² + 12²) ÷ 73 + 895
= (100 + 121 + 144) ÷ 73 + 895
= 365 ÷ 73 + 895
= 5 + 895
= 900
2) 2555 ÷ (13² + 14²) + 35
= 2555 ÷ (169 + 196) + 35
= 2555 ÷ 365 + 35
= 7 + 35
= 42
