All I've got so far is x^1/3 = 10.
How do you find the power of X from there? in easy terms please :)
Thanks in advance :D
3 + x^1/3 = 13, What is the power of X?

✔ 最佳答案
3 + x^(1/3) = 13x^(1/3) = 13 - 3
x = 10^(3/1)
x = 10^3
x = 1000

x^(1/3) = 10
x = 10 ³
x = 1000
x = 10 ³
x = 1000

3-3+X^1/3=13-3 (both side i had less three )
X^1/3=10
X^3/3=10^3 (let both side ^3 to makeX)
X=1000 (10*10*10=1000)
X^1/3=10
X^3/3=10^3 (let both side ^3 to makeX)
X=1000 (10*10*10=1000)

i dont understand what you mean by power of x, since the power of x is supposed to be 1/3, as stated in the question.
But given the equation, the value of x can be achieved.
x^1/3 = 10
raising both sides to the power of 3.
(x^1/3)^3 = 10^3
x=10^3=1000.
But given the equation, the value of x can be achieved.
x^1/3 = 10
raising both sides to the power of 3.
(x^1/3)^3 = 10^3
x=10^3=1000.

3 + x^(1/3) = 13
3 - 3 + x^(1/3) = 13 - 3
x^(1/3) = 10
[x^(1/3)]^3 = 10^3
x^(3/3) = 1000
x = 1000
3 - 3 + x^(1/3) = 13 - 3
x^(1/3) = 10
[x^(1/3)]^3 = 10^3
x^(3/3) = 1000
x = 1000

x = 1000
root of the third order
You must powerd to 3
(x^(1/3))^3 = x
root of the third order
You must powerd to 3
(x^(1/3))^3 = x
