" (d) "3x^(3)-243xy^(2)

Factorize each of the following expressions: 256x^(5)-81x(2)a^(4)-(2b+c)^(4)(3x+4y)^(4)-x^(4)(4)p^(2)q^(2)-p^(4)q^(4)3x^(3)y-243xy^(3)(6)a^(4)b^(4)-16c^(4)

3a^(2)b-243ab^(2)

[" 2.If two positive integers "a" and "b" are written as "a=x^(3)y^(2)" and "b=xy^(3);x,y" are prime "],[[" numbers,then "HCF(a,b)" is "," (c) "x^(3)y^(3)],[" (a) "xy," (b) "xy^(2)," (d) "x^(2)y^(2)]]

Add : x^(3) - x^(2)y + 5xy^(2) + y^(3) , -x^(3) - 9xy^(2) + y^(3), 3x^(2)y + 9xy^(2)

If 9+2(3x-xy+x^(2))+y^(2)=0 ,then what is the value of (3x^(2)-2xy+5y^(2)) ?

Add 2x^(2)+5xy-2y^(2), 3x^(2)-2xy+5y^(2) and 2x^(2)+8xy+3y^(2)

Differentiate w.r.t x x^(3) + x^(2)y+ xy^(2) + y^(3) = 81

Given that f(x,y)=x^(3)y . Find f_(xy) (A) 2xy (B) x^(2) (C) 3x^(2) (D) None of these

Perform the division: (x ^(3) y ^(3) + x ^(2) y ^(3) - xy ^(4) + xy)div xy
