Exercise 20 (C) | Q 2.1

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

xy − bd = ..............

Find the value of 3a − 2b, when a = 8 and b = 10

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 6a − 3b − 4c − 2d

If a = 3, b = 0, c = 2 and d = 1, find the value of ab − bc + cd − da

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

`"x"/(2"x"^2)`

Evaluate:

(23 – 15) + 4

If x = 2, y = 3 and z = 4, find the value of 3x² – 4y² + 2z².

If x = 3, y = 2 and z = 1; find the value of y² – x² + 6z²

If x = − 3, find the value of 2x³ + 8x² – 15.
