Hi good people!,
Please help me out here...Solve for x in the equation:
x13=41x3
what I did was raise everything to another power of 3,
x=641x9,
then multiplied by x9
x10=64,
then I'm stuck...
Here is my solution.
x13=y
y = 4 / y
y^2 = 4
y = 2
x13=2
x = the cube root of 2
I hope this helped,
Gavin
Solve for x:
x^(1/3) = 4/x^3
Raise both sides to the power of three:
x = 64/x^9
Cross multiply:
x^10 = 64 Take the 10th root of both sides
x = 2^(3/5) or x= (-2)^(3/5)
These 2 solutions are the only real solution to balance the equation.
x^{1 \over3}=4{1 \over x^3}
x13=41x3x13=4x−3x=43∗x−9x10=43x=43/10x=23/5x=5√8x≈1.5157
this is the only positive real answer.
I think our guest's negative answer also works. It may not work with convention though
The cube root is in the question. so is a negative allowed.. I am not sure.
I think there are other complex answers as well.
Hi Melody,
a Million thank you's...I think your answer is closest to what I believe the answer should be. I do appreciate!
One more try:
ax13=41x3
definition:
is 413=4+13 so is 41x3=4+1x3
x13=4+1x3 | ×x3
x103=4x3+1
f(x)=4x3−x103+1≠0
The function has a minimum in P (0;1).
The function has no zero.

asinus,
wow, this is something else!!..would never have thought of going that route. I do appreciate your help! Thank you..
