Fill in the blank, when:
x = 3, y = 6, z = 18, a = 2, b = 8, c = 32 and d = 0.
`"y"/"x"` = ...........
Find the value of `"yx"/"z"`, when x = 8, y = 4 and z = 16
Find the value of 5x2 – 3x + 2, when x = 2.
If x = 2, y = 5 and z = 4, find the value of the following:
`(5"x"^4"y"^2"z"^2)/(2"x"^2)`
Simplify:
25y − (5x − 10y + 6x − 3y)
Simplify:
`"a"−[−{−(a−overline("b"-"c"))}]`
Simplify:
3x − [5y − {6y + 2 (10y − x)}]
If P = − 12x2 – 10xy + 5y2, Q = 7x2 + 6xy + 2y2, and R = 5x2 + 2xy + 4y2 ; find P – Q + R
Simplify:
3x – 6 {3x – 8 (5x – 10)}
Simplify:
`8"x"−(3"x"−overline(2"x"-3))`
