\(10^2+3\cdot\left\{12^2-4\cdot\left[\left(5^7:5^6-5^0\right)\right]+1\right\}\)
\(=100+3\cdot\left\{144-4\cdot\left[\left(5-1\right)+1\right]\right\}\)
\(=100+3\cdot\left[144-4\cdot\left(4+1\right)\right]\)
\(=100+3\cdot\left(144-4\cdot5\right)\)
\(=100+3\cdot\left(144-20\right)\)
\(=100+3\cdot124\)
\(=100+372\)
\(=472\)
