assuming you meant
I=V/√(R^2+wL^2)
I^2 = V^2 / (R^2 + wL^2)
I^2/V^2 = 1/(R^2 + wL^2)
R^2 + wL^2 = V^2/I^2
now finish it off
Make R the subject of the following formula: I=V/√R^2+wL^2

I bet you mean
I=V/√ (R^2+wL^2 )
if so then
√ (R^2+wL^2 ) = V/I
R^2+wL^2 = V^2 / I^2
R^2 = V^2/I^2 - w L^2
R = +/- √ (V^2/I^2 - w L^2)
I=V/√ (R^2+wL^2 )
if so then
√ (R^2+wL^2 ) = V/I
R^2+wL^2 = V^2 / I^2
R^2 = V^2/I^2 - w L^2
R = +/- √ (V^2/I^2 - w L^2)
