Fill in the blank, when:
x = 3, y = 6, z = 18, a = 2, b = 8, c = 32 and d = 0.

y × d = .............

Find the value of `"yx"/"z"`, when x = 8, y = 4 and z = 16

Find the value of `("a+b"-"c")/(2"a")`, when a = 5, b = 7 and c = 2

If a = 3, b = 0, c = 2 and d = 1, find the value of 3a + 2b − 6c + 4d

Simplify:

`5"x"^2-(3"x"-overline("x"^2-4))`

If x = 3, y = 2 and z = 1; find the value of y^x

If x = 3, y = 2 and z = 1; find the value of xy + y²z – 4zx

If P = − 12x² – 10xy + 5y², Q = 7x² + 6xy + 2y², and R = 5x² + 2xy + 4y²; find P – Q + R

Multiply and then evaluate:

(x² – y) and (xy – y²); when x = 1 and y = 2.

Simplify:

3x – 6 {3x – 8 (5x – 10)}
