a) \(\left(792,81\times0,25+792,81\times0,75\right)\times\left(11,9-900\times0,01-2,9\right)\)
\(=792\times\left(0,25+0,75\right)\times\left(11,9-9-2,9\right)\)
\(=792\times1\times0=0\)
b) \(\dfrac{40,2\times8,1\times48}{0,048\times0,81}=\dfrac{40,2\times8,1\times48}{48\times0,001\times8,1\times0,1}\)
\(=\dfrac{40,2}{0,0001}=402000\)
a) \(\left(792,81\times0,25+792,81\times0,75\right)\times\left(11,9-900\times0,01-2,9\right)\)
\(=\left[792,81\times\left(0,25+0,75\right)\right]\times\left(11,9-9-2,9\right)\)
\(=\left[792,81\times1\right]\times2,9-2,9\)
\(=792,81\times0\)
\(=0\)

b) \(\dfrac{40,2\times8,1\times48}{0,048\times0,81}=\dfrac{40,2\times10000\times0,81\times0,048}{0,048\times0,81}=40,2\times10000=402000\)
