y=(sqrt(x)(3x+5)^(2))/(sqrt(x+1))

y=(sqrt(3x-5)-(1)/(sqrt(3x-5)))^(5)

Which of the following expressions are polynomials ? In case of a polynomial write its degree. (i) x^(3)-5x+2 (ii) y^(2)+sqrt(2)y-sqrt(5) (iii) 2sqrt(x)+7 (iv) -6 (v) 4t^(2)+(1)/(6)t+2sqrt(3) (vi) z^(2)+(5)/(z^(2))+1 (vii) (1)/(3x) (viii) 1-sqrt(5x) (ix) (1)/(4x^(-2))+3x+5 (x) (6sqrt(x)+x^(3//2))/(sqrt(x))

((sqrt(x))^((3)/(5))times(sqrt(x))^((2)/(5))+2sqrt(x))/(2(sqrt(x))^((2)/(3))times(sqrt(x))^((1)/(3))+sqrt(x))=

y=sqrt(x^(2)-3x+2)+(1)/(sqrt(3+2x-x^(2))) find the domain =?

Find y ' , if (a) y=5x^(2//3)-3x^(5//2)+2x^(-3) (b) y=(a)/(3sqrt(x))^(2)-(b)/(x^(3)sqrt(x) (a,b constants )

min[(x_(1)-x_(2))^(2)+(3+sqrt(1-x_(1)^(2))-sqrt(4x_(2)))],AA x_(1),x_(2)in R is (a)4sqrt(5)+1 (b) 3-2sqrt(2)(c)sqrt(5)+1(d)sqrt(5)-1

Simplify : (a) sqrt(y+sqrt(2xy-x^(2))) + sqrt(y-sqrt(2xy-x^(2))) (b) (x+sqrt(x^2-1))/(x-sqrt(x^(2)-1)) -(x-sqrt(x^(2)-1))/(x+sqrt(x^(2)-1))

find x and y 3/sqrt(x)+1/sqrt(x)=sqrt(x) y^2-(7)^(5/2)/sqrt(y)=0
