giúp mình với

Answer 1

\(1,54\times94+92\times15,4\times0,1+1,54\times8-1,54\times184\\ =1,54\times94+92\times1,54+1,54\times8-1,54\times184\\ =1,54\times\left(94+92+8-184\right)\\ =1,54\times10\\ =15,4\)

Answer 2

1,54x94+92x15,4x0,1+1,54x8-1,54x184
\(=0,1.1,54.\left(94+92+8-184\right)\)
\(=10.1,54.10\)
\(=1,54.100=154\)
