Do you mean x^4 = 8?
If so then x = 4th root of 8 (= 8^(¼))
≈1.6818
Otherwise x = 8/4 = 2

Is that x times 4 = 8 or is it x to the 4th power = 8?

if the question is X^4 = 8 then the answer would be
X = 4th root(8)

Are you just multiplying x by 4? If so, to solve for x just multiply both sides by 1/4 to get x=2.
Your question must have meant something else. Is it because normally we'd write 4x? Multiplication is communitive and so you can write it either way.

Do you mean x*4=8 or x^4=8?
x*4=8
x=2
x^4=8
x=8^.25=1.682

see x4=8
so x=8/4
the ans will be x=2

Look at it this way:
4x = 8 (legal since ab = ba)
The solution is left two you.
