a)\(48x19+48x115+134x52\)
\(=48x\left(19+115\right)+134x52\)
\(=48x132+132x52\)
\(=132x\left(48+52\right)\)
\(=132x100=13200\)
b)\(27x121-87x27+73x34\)
\(=27x\left(121-87\right)+73x34\)
\(=27x34+73x34\)
\(=34x\left(27+73\right)\)
\(=34x100=3400\)
c)\(125x98-125x46-52x25\)
\(=125x\left(98-46\right)-52x25\)
\(=125x52-52x25\)
\(=52x\left(125-25\right)\)
\(=52x100=5200\)
d)\(136x23+136x17-40x36\)
\(=136x\left(23+17\right)-40x36\)
\(=136x40-40x36\)
\(=40x\left(136-36\right)\)
\(=40x100=4000\)
e)\(17x93+116x83+17x23\)
\(=17x\left(93+23\right)+116x83\)
\(=17x116+116x83\)
\(=116x\left(17+83\right)\)
\(=116x100=11600\)
g)\(19x27+47x81+19x20\)
\(=19x\left(27+20\right)+47x81\)
\(=19x47+47x81\)
\(=47x\left(19+81\right)\)
\(=47x100=4700\)
