a) ( 14678:2+2476).(2576-2575)
= ( 7329 +2476).1
= 9805 .1
= 9805
b) (195-13.15):(1945+1014)
= (195- 195 ):2959
= 0 :2959
=0
\(\left(14678:2+2476\right).\left(2576-2575\right)\)
\(=\left(7339+2476\right).\left(2576-2575\right)\)
\(=9875.1=9875\)
\(\left(195-13.15\right):\left(1945+1014\right)\)
\(=\left(195-195\right):\left(1945+1014\right)\)
\(=0:\left(1945+1014\right)=0\)
