\(a.\left(236,4\times10,2-46,25:5\right)\times\left(24,1\times4-48,2:5\right)\)
\(=\left(2411,28-9,25\right)\times\left(96,4-9,64\right)\)
\(=2402,03\times86,76\)
\(=208400,1228\)
\(b.62,92:5,2-4,2\times\left(7-6,3\right)\times3,67-1,21\)
\(=62,92:5,2-4,2\times0,7\times3,67-1,21\)
\(=12,1-2,94\times3,67-1,21\)
\(=12,1-10,7898-1,21\)
