132:0,125+132:0,25-132:0,2+132:0,5+132

=  132*8+132*4-132*5+132*2+132*1

=  132*(8+4-5+2+1)

=  132*10

=  1320

kb với mình nhé!

132 : 0,125 + 132 : 0,25 -132 : 0,2 + 132 : 0,5 +

=132 : 0,125 + 132 : 0,25 -132 : 0,2 + 132 : 0,5 + 132 . 1

=132(0,125+0,25-0,2+0,5+1)

=132.1,675

=221,1

xin lỗi mk nhầm đề

Bạn hoàng trúc nhi làm đúng rùi đấy

123*54+132*45+132=123*54+(45+1)*132

=123*54+46*132

=123*54+46*(123+9)

=123*54+46*123+46*9

=123*(54+46)+414

=123*10+414

=1230+414

=1644

\(123+132+213+312+321\)

\(=\left(123+312\right)+\left(213+132\right)+321\)

\(=435+345+321\)

\(=\left(435+345\right)+321\)

\(=780+321=1101\)

123+132+213+231+312+321

=(123+321)+(213+132)+321

=435+345+321

=(435+345)+321

=780+321

=1101

123 + 132 + 213 + 231 + 312 + 321

= 123 + 132 + 213 + 312 + 231 + 321

= 255 + 525 + 552

= 780 + 552

= 1232

\(A=132\times53+132\times47\)

\(\Leftrightarrow A=132\left(53+47\right)\)

\(\Leftrightarrow A=132\times100\)

\(\Leftrightarrow A=13200\)

\(\text{Vậy }A=13200\)

\(B=204\times13-204\times3\)

\(\Leftrightarrow B=204\left(13-3\right)\)

\(\Leftrightarrow B=204\times10\)

A) 132*53+132*47

=132*(53+47)

=132*100

=13200

B) 204*13-204*3

=204*(13-3)

=204*10

a) \(\frac{28.36}{27.14}=\frac{7.4.9.2.2}{3.9.7.2}=\frac{4.2}{3}=2\)

b) \(\frac{132.45.8}{25.16.99}=\frac{2.2.3.11..3.3.5.2.2.2}{5.5.2.2.2.2.3.3.11}=\frac{2.3}{5}=\frac{6}{5}\)

a) 744 x 24 + 628 x 48

=372 x2 x 24 + 628 x 48

= 48 x (372 + 628)

=      48 x 1000

=        48 000

b) 8 x 132 x 125

=  8 x 125 x132

= 1 000  x 132

=    132 000

Khó quá!
