71

gọi số cần tìm là a 

ta có

vì 13-5=8

    29-13=16

do đó ta thấy :

16 : 8 = 2

=> khoảng cách giữa các số về sau sẽ x2

=> 16 x 2 = 32

=> 29 + 32 = a = 61

  vậy số cần tìm là 61

\(\dfrac{30\times25\times7\times8}{75\times8\times12\times14}\\ =\dfrac{6\times5\times25\times7\times8}{25\times3\times8\times2\times6\times2\times7}\\ =\dfrac{5}{3\times2\times2}\\ =\dfrac{5}{12}\)

\(\dfrac{30\times25\times7\times8}{75\times8\times12\times14}\)

\(=\dfrac{2\times3\times5\times5\times5\times7\times2\times2\times2}{5\times5\times3\times2\times2\times2\times2\times2\times3\times7\times2}\)

\(=\dfrac{5}{2\times3\times2}\)

\(=\dfrac{5}{12}\)

a, Những kẻ yếu đuối, vật lộn cật lực

b, Những chú ếch xanh 

c, Những kẻ mới đến

d, Đám hoa bìm bìm trắng

(2022 x a - 2022 )=0

a = 1

= 142 x 42 + 142 x 58 

= 5964 + 8236

= 14200

= 142 x 42 + 142 x 58 

=  5964      + 8236

=  14200

Tick giúp mình nha

\(A=\dfrac{34,4\text{x}6,34+3,66\text{x}34,4}{17,2\text{x}9,55+12,45\text{x}17,2-17,2}\)

\(=\dfrac{34,6\text{x}\left(6,34+3,66\right)}{17,2\text{x}\left(9,55+12,45-1\right)}\)

\(=\dfrac{34,6\text{x}10}{17,2\text{x}21}=\dfrac{865}{903}\)
