\(\left\{25\times\left[100:4-1\left(38\times2-6\right)\right]\right\}\)

\(=\left\{25\times\left[100:4-1\left(76-6\right)\right]\right\}\)

\(=\left\{25\times\left[100:4-1\times70\right]\right\}\)

\(=\left\{25\times\left[100:4-70\right]\right\}\)

\(=\left\{25\times\left[25-70\right]\right\}\)

\(=\left\{25\times\left(-45\right)\right\}\)

\(=-1125\)
