sao bạn không giải bài cuối

giuspp mình vớiiiiiiiiiiiiii

a: \(\Leftrightarrow\left[{}\begin{matrix}n+\dfrac{1}{3}=\dfrac{1}{5}\\n+\dfrac{1}{3}=-\dfrac{1}{5}\end{matrix}\right.\Leftrightarrow\left[{}\begin{matrix}n=-\dfrac{2}{15}\\n=-\dfrac{8}{15}\end{matrix}\right.\)

12 = 2² . 3

30 = 2 . 3 . 5

ƯCLN ( 12 ; 30 ) = 2 . 3 = 6

8 = 2³

9 = 3²

ƯCLN ( 8 ; 9 ) = 1

8 = 2³

12 = 2² . 3

15 = 3 . 5

ƯCLN ( 8 ; 12 ; 15 ) = 1

24 = 2³ . 3

16 = 2⁴

8 = 2³

ƯCLN ( 24 ; 16 ; 8 ) =2³ = 8

1)

a) 18 = 2.3²

30 = 2.3.5

ƯCLN(18; 30) = 2.3 = 6

b) 24 = 2³.3

48 = 2⁴.3

ƯCLN(24; 48) = 2³.3 = 24

c) 18 = 2.3²

30 = 2.3.5

15 = 3.5

ƯCLN(18; 30; 15) = 3

d) 24 = 2³.3

48 = 2⁴.3

36 = 2².3²

ƯCLN(24; 48; 36) = 2².3 = 12

2) a) 174 = 18 . 9 + 12

18 = 12 . 1 + 6

12 = 6 . 2

Vậy ƯCLN(174; 18) = 6

b) 124 = 16 . 7 + 12

16 = 12 . 1 + 4

12 = 4 . 3

⇒ ƯCLN(124; 16) = 4

⇒ BCNN(124; 16) = 124 . 16 : 4 = 496

60/36=15/9

12

7

1

1

24 = 2³.3; 60 = 2².3.5

ƯCLN(24; 60) = 2².3 = 12

35 = 5.7; 7 = 7

ƯCLN(35; 7) = 7

24 = 2³.3; 23 = 23

ƯCLN(24; 23) =1

35 = 5.7

7 = 7

1 =1

ƯCLN(35; 7; 1) =1

=2220 nha

555 + 555 + 555 + 555 = 555 * 4 = 2220

k nhé

555+555+555+555=2220

k nha
