Expand `(x+y)^(4)-(x-y)^(4)`. Hence find the value of `(3+sqrt(5))^(4) -(3-sqrt(5))^(4)`.

Using binomial theorem,expand {(x+y)^(5)+(x-y)^(5)}* and hence find the value of {(sqrt(2)+1)^(5)+(sqrt(2)-1)^(5)}

Using binomial theorem, expand [ ( x+y)^(5) + (x-y)^(5) ] and hence find the value of [ ( sqrt(3) + 1)^(5) - ( sqrt(3) - 1)^(5) ] .

Expand: (4x+5y)^3

Find (x+a)^(3)-(x-a)^(3) . Hence evaluate (sqrt(5)+sqrt(4))^(3)-(sqrt(5)-sqrt(4))^(3)

Find (x+a)^(3)-(x-a)^(3) . Hence evaluate (sqrt(5)+sqrt(4))^(3)-(sqrt(5)-sqrt(4))^(3)

Find the value of x' if 3sqrt(4x-5)-5=0

Using binomial theorem, expand {(x+y)^5+(x-y)^5}dot and hence find the value of {(sqrt(2)+1)^5+(sqrt(2)-1)^5}dot

Expand : (3x+4y)(3x+5y)
