I. ` (x)^(2) = 961" "` II. ` y = sqrt(961) `

I. x^(2)=16 II. y=sqrt(16)

I. x^2-7 sqrt7x+84=0 II. y^2-5 sqrt5 y+30=0

(i) 2x^(3) = sqrt(256) II. y^(2) -9y+14 = 0

If x and y are rational and if x (3 + 2 sqrt2) - y sqrt2 = y(5 -3 sqrt2) + 7(2 + x sqrt2) , then find the value of x and y

Differentiate with respect to X (i) y=xlnx " " (ii) y=x^(2)e^(x) " " (iii) y=(sin x)/(x) " " (iv) y=(3x^(2)+2sqrt(x))/(x)

In each of the following questions, two equations are given. You have to solve them "I. "sqrt(961)x+1234=1486" II. "sqrt(1024)y-1196=1001

Convert the following improper fractions into mixed numbers : (i) 17/3" (ii) " 119/15" (iii) "961/13" (iv) " 117/32

A student was asked to find sqrt(961). He read it wrongly and found sqrt(691) to the nearest integer.How much small was his number from the correct answer?
