8*(2x)/(a)+(y)/(b)=2,(x)/(a)-(y)/(b)=4

2(x/a)+(y/b)=2; (x/a)-(y/b)=4

If x=2 and y=4, then ((x)/(y))^(x-y)+((y)/(x))^(y-x)=4(b)8(c)12(d)2

If (x)/(y)=(a+2)/(a-2), then (x^(2)-y^(2))/(x^(2)+y^(2)) is equal to (8a)/(a^(2)+4)(b)(4a)/(a^(2)-4)(c)(4)/(a^(2))(d)(4a)/(a^(2)+4)

Factorize each of the following algebraic expressions: (x-y)^(2)+(x-y)6(a+2b)-4(a+2b)^(2)a(x-y)+2b(y-x)+c(x-y)^(2)-4(x-2y)^(2)+8(x-2y)

If x=2\ \ and y=4, then (x/y)^(x-y)+\ (y/x)^(y-x)= (a) 4 (b) 8 (c) 12 (d) 2

2(a x-b y)+(a+4b)=0 , 2(b x+a y)+(b-4a)=0

The following are the steps involved in factorizing 64 x^(6) -y^(6) . Arrange them in sequential order (A) {(2x)^(3) + y^(3)} {(2x)^(3) - y^(3)} (B) (8x^(3))^(2) - (y^(3))^(2) (C) (8x^(3) + y^(3)) (8x^(3) -y^(3)) (D) (2x + y) (4x^(2) -2xy + y^(2)) (2x - y) (4x^(2) + 2xy + y^(2))

Find the square root of: (144(a+b)^(8)(x-y)^(4))/(64(a-b)^(2)(x+y)^(6))

Factorize each of the following algebraic expressions: (1) (x-y)^2+(x-y) (2) 6(a+2b)-4(a+2b)^2 (3) a(x-y)+2b(y-x)+c(x-y)^2 (4) -4\ (x-2y)^2+8(x-2y)
