If x and y are integers, what is x + y ? (1) 3^x = 81 (2) 5^x = (25)/(5^y)

Verify that (3x + 5y) ^(2) - 30 xy= 9x ^(2) + 25 y ^(2)

Find the products: (3/x-5/y)(9/(x^2)+(25)/(y^2)+(15)/(x y))

(x-4)(x-3)=(x-6)(x-5) (y-9)(y-3)= (y-4)(y-3)

The value of (5x-3y)^(2)-(5x+3y)^(2) when x=-1,y=sqrt(1/(25)) is

Find each of the following products: (i) (x - 4)(x - 4) (ii) (2x - 3y)(2x - 3y) (iii) ((3)/(4) x - (5)/(6) y) ((3)/(4)x - (5)/(6) y) (iv) (x - (3)/(x)) (x - (3)/(x)) (v) ((1)/(3) x^(2) - 9) ((1)/(3) x^(2) - 9) (vi) ((1)/(2) y^(2) - (1)/(3) y) ((1)/(2) y^(2) - (1)/(3) y)

Find the product: (3x-5y-4)(9x^(2)+25y^(2)+15xy+12x-20y+16)

Solve 11(x - 5) + 10(y - 2) + 54 = 0 7(2x - 1) + 9 (3y - 1) = 25
