The expression `3(a^2+1)^2+(2(a-1)(a^2+1)-5(a-1)^2-4(0.75a^4+3a-1)` when sinplified redues to

The expression 3(a^2+1)^2+2(a-1)(a^2+1)-5(a-1)^2-4(0.75a^4+3a-1) when simplified reduces to

The expression (2^(2)+1)/(2^(2)-1)+(3^(2)+1)/(3^(2)-1)+(4^(2)+1)/(4^(2)-1)+((2011)^(2)+1)/((2011)^(2)-1) lies in the interval

if [{:(3,2),(7,5):}]A{:[(-1,1),(-2,1):}]={:[(2,-1),(0,4):}] then trace of A is equal to

if [{:(3,2),(7,5):}]A{:[(-1,1),(-2,1):}]={:[(2,-1),(0,4):}] then trace of A is equal to

If A = [(1,5,3),(2,4,0),(3,-1,-5)], B = [(2,-1,0),(0,-2,5),(1,2,0)] then find 3A - 4B .
