\(107-\left\{38+\left[7.3^2-24:6+\left(9-7\right)^3\right]\right\}:15\)
\(=107-\left\{38+\left[7.3^2-24:6+2^3\right]\right\}:15\)
\(=107-\left\{38+\left[7.3^2-4+2^3\right]\right\}:15\)
\(=107-\left\{38+\left[63-4+2^3\right]\right\}:15\)
\(=107-\left\{38+\left[59+2^3\right]\right\}:15\)
\(=107-\left\{38+67\right\}:15\)
\(=107-105:15\)
\(=107-7\)
\(=100\)
107 – {38 + [7.32 – 24 : 6+(9 – 7)3]}:15
= 107 - {38+ [7.32 - 24 : 6 + 23 ]} : 15
= 107 - {38 + [ 7.9 - 24 : 6 + 8]} :15
= 107 - {38+[ 63 - 4 + 8]} : 15
= 107 - {38 + 67} : 15
= 107 - 105 : 15
= 107 - 7
= 100
17) 10 – [(82 – 48).5 + (23.10 + 8)] : 28 - 70
= 10 - [(64 - 48).5 + (8.10 +8)] : 28 - 70
= 10 - [16.5 + 88] : 28 - 70
= 10 - [80 + 88] : 28 - 70
= 10 - 168 : 28 - 70
