(4)/(9)a^(2)+b^(2)+(4)/(3)ab-73007 pi a

Multiply : -(2)/(3)a^(7)b^(2) and -(9)/(4)ab^(5)

If a^(4) + a^(2) b^(2) +b^(4)=8, a^(2) + b^(2) + ab= 4 find ab

The possible values of theta in (0, pi) such that sin (theta) + sin (4 theta) + sin (7 theta) = 0 are (1) (2 pi) / (9), (i) / (4 ), (4 pi) / (9), (pi) / (2), (3 pi) / (4), (8 pi) / (9) (2) (pi) / (4), (5 pi ) / (12), (pi) / (2), (2 pi) / (3), (3 pi) / (4), (8 pi) / (9) (3) (2 pi) / (9 pi) ), (pi) / (4), (pi) / (2), (2 pi) / (3), (3 pi) / (4), (35 pi) / (36) (4) (2 pi ) / (9), (pi) / (4), (pi) / (2), (2 pi) / (3), (3 pi) / (4), (8 pi) / (9)

What is the HCF of a^(2)b^(4)+2a^(2)b^(2) and (ab)^(7)-4a^(2)b^(9) ?

Simplify : (2a+3b+4c) ( 4a^(2) + 9b^(2) + 16c^(2) -6ab - 12bc - 8ca )

If a+b=1 , then a^(4)+b^(4)-a^(3)-b^(3)-2a^(2)b^(2)+ab is equal to :

If a^(4) + a^(2)b^(2) + b^(4) = 12, a^(2) + ab+ b^(2)=4 , find ab

Simplify ((7)/(9)a - (4)/(3) b) ^(2) -ab
