Question

48,16 x 8 + 27,15 x 4 + 2 x 48,16 + 27,15 x 6 

giúp mình bài này nha mình cần gấp

 

Answer 1

=48,16(8+2)+27,15(4+6)

=10(48,16+27,15)=75,31*10=753,1

Answer 2

Bằng 753,1.

Answer 3

48,16 x 8 + 27,15 x 4 + 2 x 48,16 + 27,15 x 6 

\(=\left(48,16\cdot8+2\cdot48,16\right)+\left(27,15\cdot4+27,15\cdot6\right)\)

\(=48,16\left(8+2\right)+27,15\left(4+6\right)\)

\(=48,16\cdot10+27,15\cdot10\\ =10\cdot\left(48,16+27,15\right)\\ =10\cdot75,31\\ =753,1\)

Answer 4

\(48,16\times8+27,15\times4+2\times48,16+27,15\times6\)

\(=48,16\times\left(8+2\right)+27,15\times\left(4+6\right)\)

\(=48,16\times10+27,15\times10\)

\(=481,6+271,5\)

\(=753,1\)

Answer 5

48,16(8+2)+27,15(4+6)

=10(48,16+27,15)=75,31*10=753,1
