Move items and get x? =8 1
Square both sides at the same time, x = 9.
∴x 1=9 x2=-9
(2)9x? = 1
x? = 1/9 x = 1/3 ∴x 1= 1/3 x2 =- 1/3
(3) The cubic of x =0.00 1.
If both sides are open at the same time, x=0. 1.
(4) The cube of (x-1) is 8.
If both sides are open at the same time, X- 1=2.
∴x=3
(5)27x cubic =8
Divide both sides by 27 to get x 3 = 8/27.
If both sides are open at the same time, x=2/3.
(6)│x│=√ 10 simplification
There are two numbers whose absolute values are equal to ∵ 10. They are a pair of opposites, namely ∵ 10.
∴ X = √ 10 after removing the absolute value sign.
∴x 1=√ 10 x2 =-√ 10
