Question

4+{8+2×[3+(10+2×7)÷8]} responda

Answer 1

$4+[8+2.[3+(10+2.7):8]]= \\ \\ =4+[8+2.[3+(10+14):8]]= \\ \\ =4+[8+2.[3+24:8]]= \\ \\ =4+[8+2.[3+3]]= \\ \\ =4+[8+2.6]= \\ \\ =4+[8+12]= \\ \\ =4+20=24$

Answer 2

4 + {8 + 2x[3+(10+2x7):8]} = 
4 + {8 + 2x[3+(10+14):8]} = 
4 + {8 + 2x[3+(24:8)]} = 
4 + {8 + 2x[3 + 3]} = 
4 + {8 + 2x6} = 
4 + {8 + 12} = 
4 + 20 = 24
