13.25 x 2 + 13.25 x 4 + 13.25 x 2 x 8

= 13.25 x 2 + 13.25 x 4 + 13.25 x 16

= 13.25 x (2+4+6)

= 13.25 x 12 = 159

   13,25 : 0,5 + 13,25 : 0,25 + 26,5 : 0,125

= 13,25 x 2 + 13,25 x 4 + 26,5 x 8

= 13,25 x ( 2 + 4 ) + 26,5 x 8

= 13,25 x 6 + 26,5 x 8

= 13,25 x 6 + 13,25 x 2 x 8 

= 13,25 x 6 + 13,25 x ( 2 x 8 )

= 13,25 x 6 + 13,25 x 16

= 13,25 x ( 6 + 16 )

= 291,50

= 13,25 x 22

=  291,50  

13,25 : 0,5 + 13,25 : 0,25 + 13,25 : 0,125
=13.25*2+13.25*4+13.25*8
=13.25*(2+4+8)
=13.25*14
=185.5

\(13,25\div0,25+13,25\div0,25+13,25\div0,125+13,25\div0,25\)

\(=13,25\times2+13,25\times4+13,25\times8+13,25\times4\)

\(=13,25\times\left(2+4+8+2\right)\)

\(=13,25\times16\)

\(=212\)

P/s : Tính ra kết quả luôn == Sai thì thôi nha :>

\(13,25\div0,5+13,25\div0,25+13,25\div0,125-13,25\div0,25\)

\(=13,25\cdot2+13,25\cdot4+13,25\cdot8-13,25\cdot4\)

\(=13,25\left(2+4+8-4\right)\)

\(=13,25\cdot10\)

\(=132,5\)

13,25 . 10 + 13 . 4 + 0,25 . 4

= 132,5 + 52 + 1 

= 185,5

\(=\dfrac{1}{10}+\dfrac{1}{2}\times2-\dfrac{1}{4}\times4+\dfrac{1}{8}\times8\)

\(=\dfrac{1}{10}+1-1+1\)

\(=\dfrac{1}{10}+1=\dfrac{1}{10}+\dfrac{10}{10}=\dfrac{11}{10}\)
