Solve for y
y=\frac{1}{8x^{2}}
x\neq 0
Solve for x (complex solution)
x=-\frac{\sqrt{2}y^{-\frac{1}{2}}}{4}
x=\frac{\sqrt{2}y^{-\frac{1}{2}}}{4}\text{, }y\neq 0
Solve for x
x=\frac{\sqrt{\frac{2}{y}}}{4}
x=-\frac{\sqrt{\frac{2}{y}}}{4}\text{, }y>0

2^{3}x^{2}y=1
To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.
8x^{2}y=1
Calculate 2 to the power of 3 and get 8.
\frac{8x^{2}y}{8x^{2}}=\frac{1}{8x^{2}}
Divide both sides by 8x^{2}.
y=\frac{1}{8x^{2}}
Dividing by 8x^{2} undoes the multiplication by 8x^{2}.
