sos cố gắng giúp mik vs . mình cảm ơn
Tìm y biết \(\left(\frac{1}{2x4}+\frac{1}{4x6}+\frac{1}{6x8}+\frac{1}{8x10}\right).y=\frac{1}{3}\)
Tính :
N = ( 1/2x4 + 1/4x6 + 1/6x8 + 1/8x10 + ....... + 1/98 X 100 ) : ( 1/2 + 1/4 + 1/8 + 1/16 + ........ + 1/512 )
(1/2x4+1/4x6+1/6x8+1/8x10)xy=1/3
(1/2x4+1/4x6+1/6x8+......+1/98x100) : y=147/50
Tìm y
(1phan 2x4+1 phan 4x6+1 phan 6x8+1phan 8x10)xy 1phan 3
[1/2x4+1/4x6+1/6x8+......+1/98x100]:y=147/50
( 1/2x4+1/4 x 6+1/6x8+....+1/98 x 100) / y = 147/50 tìm y
