`(x/10+y)(x/10-y)=?`

(x + y) ^ (10) = x ^ (8) y ^ (2)

Find the inverse of the function : y=(10^(x)-10^(-x))/(10^(x)+10^(-x))+1

(44)/(x+y)+(30)/(x-y)=10(55)/(x+y)+(40)/(x-y)=13

x+y=10; 2x-3y=0

Consider the following statements : 1. The HCF of x + y and x^(10) - y^(10) is x + y 2. The HCF of x + y and x^(10) + y^(10) is x + y 3. The HCF of x - y and x^(10) + y^(10) is x - y 4. The HCF of x - y and x^(10) - y^(10) is x - y Which of the statements given above are correct ?

All soutions o the equations x^2+y^2-8x-8y=20 and xy+4x+4y=40 satisfy the following equation (s) (A) x+y=10 (B) |x+y|=10 (C) |x-y|=10 (D) x+y=-10

Find whether the following system of equation has a solution or not ? x+5y=10 2x+10y=9

{:((10)/(x + y) - (4)/(x - y)= -2),((15)/(x + y) + (7)/(x - y) = 10):}
