4(a+b)-(b+b)^(2)

simplify (a - b)(a + b)(a^2 + b^2)(a^4 + b^4) (a^8 + b^8) (a^(16) + b^(16)) is:

What is (1)/(a-b) -(1)/(a+b) -(2b)/(a^(2)+b^(2))-(4b^(3))/(a^(4)+b^(4)) -(8b^(7))/(a^(8)-b^(8)) equal to ?

If a,b,c are distinct real numbers and |{:(a,a^(2),a^(4)-1),(b,b^(2),b^(4)-1),(c,c^(2),c^(4)-1):}|=0 then A) a b c = 1 B ) a b c ( a + b + c ) = 1 C ) a b c ( a + b + c ) = a b + b c + c a D) none of these

Simplify (b^(2)+3b-28)/(b^(2)+4b+4)÷(b^(2)-49)/(b^(2)-5b-14)

Simplify : (a+b)(a^(2)+b^(2))(a^(4)+b^(4))(a-b)

Prove that [[1+a^2+a^4, 1+a b+a^2b^2 ,1+a c+a^2c^2],[ 1+a b+a^2b^2, 1+b^2+b^4, 1+b c+b^2c^2],[ 1+a c+a^2c^2, 1+b c+b^2c^2, 1+c^2+c^4]]=(a-b)^2(b-c)^2(c-a)^2
