Find the arithmetic mean of the following numbers : (a) 6 and 26 (b) -2 and 18 (c) (x-y) and (x+y) (d) (x+y)^(3)" and "(x-y)^(3)

Find the arithmetic mean of the following numbers : (a) 6 and 26 (b) -2 and 18 (c) (x-y) and (x+y) (d) (x+y)^(3)" and "(x-y)^(3)

If x^(y^(z))=1, y^(z^(x))=125 and Z^(y^(x))=243 (x,y and z are natural numbers), then what is the value of 9x+10y-18z ?

Solve for x and y : (y+7)/(5)=(2y-x)/(4)+3x-5 (7-5x)/(2)+(3-4y)/(6)=5y-18

The value of x-y^(x-y) when x=2 and y=-2 is 18(b)-18(c)14(d)-14

4x = 18y , then the value of (frac(x)(y)-1) is
