64x100+50x44

=2200+6400

=8600

1026+2774

=3800

mình làm đúng ko vậy

TL:
= 3800

nhé

k mình nha

phải là 38/19 =2

dài lắm bạn ơi

mình ko biết

tìm a

a=2 mũ 41 nhân 5 mũ 38 

 a = 2⁴¹ . 5³⁸

a) \(\frac{637\times527-189}{526\times637+448}\)

\(=\frac{637\times\left(526+1\right)-189}{526\times637+448}\)

\(=\frac{637\times526+637-189}{526\times637+448}\)

\(=\frac{637+526+448}{526\times637+448}\)

\(=1\)

b) \(\frac{64\times50+44\times100}{27\times38+146\times19}\)

\(=\frac{50\times\left(64+44\times2\right)}{19\times\left(27\times2+146\right)}\)

\(=\frac{50\times\left(64+88\right)}{19\times\left(54+146\right)}\)

\(=\frac{50\times152}{19\times200}\)

\(=\frac{152}{19\times4}\)

\(=\frac{38}{19}\)

\(=\frac{2}{1}\)

\(=2\)

\(\frac{64X50+44X100}{27X38+146X19}=\frac{64X50+44X2X50}{27X2X38+146X19}=\frac{64X50+88X100}{54X38+146X19}=\frac{50X\left(64+88\right)}{19X\left(54+146\right)}=\frac{50X152}{19X200}\)\(=\frac{̸5̸̸0X152}{19X4X̸5̸0}=\frac{152}{76}=2\)                                                                                                                                                                                                                                          Đáp số :2

\(A=\left(100\times44+50\times60\right)\times\left(37414,8:1000+2242,52:100\right)\)

\(A=\left(4400+3000\right)\times\left(3741,48\times\frac{1}{100}+2242,52\times\frac{1}{100}\right)\)

\(A=7400\times\left[\frac{1}{100}\times\left(3741,48+2242,52\right)\right]\)

\(A=7400\times\frac{1}{100}\times5984\)

\(A=74\times5984\)

\(B=\left(16\times14,96\times25\right)\times\left(27\times38+19\times146\right)\)

\(B=\left(4\times4\times25\times14,96\right)\times\left(27\times19\times2+19\times146\right)\)

\(B=\left(4\times100\times14,96\right)\times\left[19\times\left(54+146\right)\right]\)

\(B=4\times1496\times19\times200\)

\(B=5984\times19\times200\)

Ta có:

 \(\frac{A}{B}=\frac{74\times5984}{5984\times19\times200}\)

\(\frac{A}{B}=\frac{37}{19\times100}\)

\(\frac{A}{B}=\frac{37}{1900}\)

Bài hơi dài, nếu có chỗ nào sai sót thì bạn thông cảm nhé

Cho \(A=\left(100\cdot44+50\cdot60\right)\cdot\left(\frac{37414,8}{1000}+2242,\frac{52}{100}\right)\)

\(B=\left(16\cdot14,96\cdot25\right)\cdot\left(27\cdot38+19\cdot146\right)\)

\(A=\left(100\cdot44+50\cdot2\cdot30\right)\cdot\left(3741,48\cdot\frac{1}{100}+2242,52\cdot\frac{1}{100}\right)\)

\(A=\left\{100.\left(44+30\right)\right\}.\left\{\left(3741,48+2242,52\right)\cdot\frac{1}{100}\right\}\)

\(A=7400\cdot5984\cdot\frac{1}{100}\)

\(A=74\cdot5984\)

\(B=\left(16\cdot14,96\cdot25\right)\cdot\left(27\cdot38+19\cdot146\right)\)

\(B=\left(4\cdot4\cdot14,96\cdot25\right)\cdot\left(27\cdot2\cdot19+19\cdot146\right)\)

\(B=100\cdot4\cdot14,96+\left\{19.\left(146+54\right)\right\}\)

\(B=1496\cdot4+19\cdot200\)

\(B=5984\cdot19\cdot200\)

=>\(\frac{A}{B}=\frac{5984\cdot74}{5984\cdot19\cdot200}\)

\(\frac{A}{B}=\frac{74}{19\cdot200}\)

\(\frac{A}{B}=\frac{37}{19\cdot100}\)( Vì giảm 200 : 2 = 100 . Lấy 74 :2 = 37 . Giảm 2 vế đi 2 lần )

=> A : B = 37/1900

Mình đã thử lại đúng nha bạn !

b)1248528

(100*44+50*54)*(37414.8/1000+2242.52/100)=265667.5052
