If Y = \( \left\{x|x\;is\;a positive\;factor\;of\;the\;number {2}^{p-1}\left({2}^{p}-1\right), where {2}^{p}-is\;a prime\;number\right\}.Write\;Y in\;the\;roaster\;form.\)
Let a, b, c and d be non-zero numbers. If the point of intersection of the line \( 4ax+2ay+c=0\) and \( 5bx+2by+d=0\) lies in the fourth quadrant and is equidistant from the two axes then: (1) \( 2bc-3ad=0\)(2) \( 2bc+3ad=0\) (3) \( 3bc-2ad=0\)(4) \( 3bc+2ad=0\)
