a: \(=703-140:\left(38+32\right)-17^{15}:17^{13}\)

\(=703-140:70-17^2\)

\(=701-289=412\)

b: \(=1024:32+140:\left(38+32\right)+23^2-7^2\)

\(=32+140:70+529-49\)

\(=32+4+480=516\)

c: \(=17^4\cdot17:17^3-14\cdot4:8\)

\(=17^2-7=289-7=282\)

1024 : 2\(^4\) + 140 : ( 38 + 2\(^5\))  - 7\(^{23}\): 7\(^{21}\)     

= 1024 : 16 + 140 : ( 38 + 32)   - 7\(^{23-21}\) 

= 64  + 140 : 70   - 7\(^2\) 

= 64 + 2   -  49 

= 17 

Ủng  hộ nha! :)  

=17 nha

đáp án của mình là -5.5854586e+17

A = ( 6888 : 56 - 11² ) . 152 _ 13 . 72 + 13 . 28

A = ( 123 - 121 ) . 152 - 13 . ( 72 + 28 )

A = 2 . 152 -  13 . 100

A = 13.100 - 304

A = 1300 - 304

A = 996

\(A=98.42-\left\{50.\left[\left(18-2^3\right):2+3^2\right]\right\}\)

\(=98.42-\left\{50.\left[\left(18-8\right):2+9\right]\right\}\)

\(=98.42-\left[50\left(10:2+9\right)\right]\)

\(=98.42-\left(50.14\right)\)

\(=4116-700=3416\)

\(B=-80-\left[-130-\left(12-4\right)^2\right]+2008^0\)

\(=-80-\left(-130-8^2\right)+1\)

\(=-80-\left(-130-64\right)+1\)

\(=-80+130+64+1\)

\(=115\)

\(C=1024:2^4+140:\left(38+2^5\right)-7^{23}:7^{21}\)

\(=1024:16+140:\left(38+32\right)-7^2\)

\(=64+140:70-49\)

\(=64+2-49=17\)

\(D=\left(2^{17}+15^4\right).\left(3^{19}-2^{17}\right).\left(2^4-4^2\right)\)

\(=\left(2^{17}+15^4\right).\left(3^{19}-2^{17}\right).\left(16-16\right)\)

\(=\left(2^{17}+15^4\right).\left(3^{19}-2^{17}\right).0\)

\(=0\)

\(E=100+98+96+....+4+2-97-95-....-3-1\)

\(=100+\left(98-97\right)+\left(96-95\right)+.....+\left(2-1\right)+\left(1-0\right)\)

\(=100+1+1+...+1+1\)

Vì lập được 49 cặp nên sẽ có 49 số 1

\(\Rightarrow E=100+1.49=100+49=149\)

alo 

a.

\(555+\left(-100\right)+\left(-80\right)+\left|-333\right|=555-100-80+333=708\)

b.

\(\left|-347\right|+\left(-40\right)+3150+\left(-307\right)=347-40+3150-307=3150\)

c.

\(1024\div2^4+140\div\left(38+2^5\right)-7^{23}\div7^{21}=2^{10}\div2^4+140\div\left(38+32\right)-7^2=2^6+140\div70-49=64+2-49=17\)

d.

\(\left(2^{17}+15^4\right)\times\left(3^{19}-2^{17}\right)\times\left(2^4-4^2\right)=\left(2^{17}+15^4\right)\times\left(3^{19}-2^{17}\right)\times\left(16-16\right)=\left(2^{17}+15^4\right)\times\left(3^{19}-2^{17}\right)\times0=0\)

sao mk ko thấy đáp số vậy bn , an làm chi tiết đ/s cho mk vs
