y =2436 nha !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
5*y:3*4+299=2599
Tìm y
Tim x biet (x-299):9,63x0,9=0,18
tim x biet (x - 299) : 9,63 x 0,9 = 0,18
tim a biet 1/2x3 + 1/3x4 + 1/4x5 +....+1/ax(a+1)=299/600
Tim x ( x - 299) : 9,63x0,9= 0,18
Ko can loi giai dau nhanh minh tick cho
Tính (299 - 301)+(298 - 300)+(297 - 299)...+(1 - 3)
tích có cách, noi facebook, mình sẽ tick
18 nhân 19 - 250 : 15 + 35 : 7 + 8
289 : 17 + 324 : 18 + 21 : 3
( 72 + 128 + 64 ) - 25 nhan 8
3500 : 50 + 9 ( 126 + 81 + 15 ) : 5
1 + 3 + 5 + 7 + ......... + 299
Tim y biet :
( y + 1/3 ) + ( y + 1/9 ) + ( y + 1/27 ) + ( y + 1/81 ) = 56/81
