Find the value of `"yx"/"z"`, when x = 8, y = 4 and z = 16
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:
`(5"x"^4"y"^2"z"^2)/(2"x"^2)`
Simplify:
12x − (5x + 2x)
Simplify:
(15b − 6b) − (8b + 4b)
Simplify:
− (− 4a − 8a)
Simplify:
`"a"-(2"a"-overline(4"a"+3"a"))`
If P = − 12x2 – 10xy + 5y2, Q = 7x2 + 6xy + 2y2, and R = 5x2 + 2xy + 4y2 ; find Q + P
Simplify:
6 {3x – 8 (5x – 10)}
Simplify:
`12"x"^2-(7"x"-overline(3"x"^2+15))`
