\(a,\left[316-\left(5^2\cdot4+16\right)\right]:\left(-2\right)^3+10\\ =\left[316-\left(25\cdot4+16\right)\right]:\left(-8\right)+10\\ =\left[316-\left(100+16\right)\right]:\left(-8\right)+10\\ =\left(316-116\right):\left(-8\right)+10\\ =200:\left(-8\right)+10\\ =-25+10\\ =-15\)
\(b,-73\cdot21+73\cdot\left(-62\right)-17\cdot73\\ =73\cdot\left(-21\right)+73\cdot\left(-62\right)-17\cdot73\\ =\left[\left(-21\right)+\left(-62\right)-17\right]\cdot73\\ =-100\cdot73\\ =-7300\)
