Evaluate `(2x-3y+5)^(3)`.

Evaluate : (2x - 5y)(2x+ 3y) for x = 2 and y = 3.

Evaluate : (x^(1//3)+y^(1//3))(x^(2//3)-x^(1//3)y^(1//3)+y^(2//3)) , when x=4(5)/(7) " and " y=5(2)/(7) .

Answer any One question : If (3x - 2y) : (x + 3y) = 5 : 6, then find the value of (2x + 5y) : (3x + 4y).

Evaluate x and y if [(x,2),(-3,y)]=2[(x^(2),1),(-(3)/(2),3y-5)] .

If (3x-5y)/(3x+5y)=1/2 find the value of (3x^2-5y^2)/(3x^2+5y^2)

If (3x-5y)/(3x+5y) = 1/2 . Then find the value of (3x^(2)-5y^(2))/(3x^(2) + 5y^(2)) .

Evaluate x and y if {:[(5,-3),(x,4)]:}={:[(y-3,-3),(2x+2,4)]:} .

Which of the following equations are consistent? If consistent, find the solutions: {:(2x + 3y = 5),(3x + 2y = 2):}
