Question 122074: My question is:
what is the cube root of x -5=3
From what I understand cube root is the same as writing 1/3
This is what I have tried to figure it out:
cube root of x -5+5=3+5
cube root of x=8
1/3x / 1/3 = 8 / 1/3
x=2.664
We are asked to change all noninteger numbers as a fraction so my final answer is:
x=2 33/50
Is this correct?
