Exercise 20 (B) | Q 1.3

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

c ÷ b = ...........

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

Show that the value of x³ – 8x² + 12x – 5 is zero, when x = 1.

State true and false:

`(2"x"-4)/("x"+1)` = − 1, when x = 1

If x = 2, y = 5 and z = 4, find the value of the following:

`("x"^2"y"^2"z"^2)/"xz"`

Evaluate:

(3y + 8y) – 5y

Simplify:

p + 2 (q − r − p)

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 2x – 3y + 4z + 5

Multiply and then evaluate:

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