Sửa câu b :

\(b,300:4+300:6-25\\ =75+50-25\\ =125-25\\ =100\)

\(a,\left(4+32+6\right)+\left(10-32-2\right)\\ =\left(10+32\right)+\left(10-32-2\right)\\ =10+32+10-32-2\\ =20-2\\ =18\\ b,300:4+300:6-25\\ =300:\left(4+6\right)-25\\ =300:10-25\\ =30-25\\ =5\\ c,17.\left[29-\left(-111\right)\right]+29.\left(-17\right)\\ =17.\left(29+111\right)+29.\left(-1\right).17\\ =17.\left(29+111-29\right)\\ =17.111=1887\\ d,19.43+\left(-20\right).43-\left(-40\right)\\ =19.43+\left(-20\right).43+40\\ =43.\left(19-20\right)+40\\ =-43+40\\ =-3\)

Ta có:

5³⁰⁰ = (5³)¹⁰⁰ = 125¹⁰⁰

Vì 125 > 34; 100 > 53 nên hiển nhiên 5³⁰⁰ > 34⁵³

Vậy....

Bài 1:

a) - | 12 - 14 | - | 98 - 15 + 2 | - 14 

= - | - 2 | - | 85 | - 14

= -2 - 85 - 14

= -101

b) ( -24 ) - ( 12 - 19 ) - | 15 - 12 - 7 |

= ( -24 ) - ( - 7 ) - | -4 |

= ( -24 ) + 7 - 4

= -21

Bài 2:

a) 5 - ( 1997 - 2005 ) + 1997

= 5 - 1997 + 2005 + 1997

= ( 5 + 2005 ) + ( 1997 - 1997 )

= 2010 + 0

= 2010

b) 1579 - ( 53 + 1679 ) - ( -53 )

= 1579 - 53 - 1679 + 53

= ( 1579 - 1679 ) + ( 53 - 53 )

= ( -100 ) + 0

= -100

c) -48725 - ( 357 - 48725 ) + 300

= -48725 - 357 + 48725 + 300

= [( -48725 ) + 48725 ] + ( 357 - 300 )

= 0 + ( -57 )

= -57

d) 4567 + ( 1234 - 4567 ) - 4

= 4567 + 1234 - 4567 - 4

= ( 4567 - 4567 ) + ( 1234 - 4 )

= 0 + 1230

= 1230

a) \(-\left|12-14\right|-\left|98-15+2\right|-14\)

\(=-\left|2\right|-\left|85\right|-14\)

\(=\left(-2\right)-85-14\)

\(=\left(-2\right)-\left(85+14\right)\)

\(=\left(-2\right)-99\)

\(=\left(-2\right)+\left(-99\right)=-101\)

5017842

( 2000 + 43 ) x 57 + ( 300 - 57 ) x 43

= 2043 x 57 + 243 x 43

= 116451 + 10449

= 126900

tk mk tk lại

6³⁰⁰+6²⁹⁹+6²⁹⁸

= 6²⁹⁸ .( 6^2+6+1)

= 6²⁹⁸ . 43 

Vì 43chia hết cho 43 => 6³⁰⁰ + 6²⁹⁹  + 6²⁹⁸  chia hết cho 43

\(=6^{298}\left(6^2+6+1\right)=6^{298}\cdot43⋮43\)
