Solve for x:

75000 (x - 1940)^(1/3) = 245000

 

Divide both sides by a constant to simplify the equation.

Divide both sides by 75000:

(x - 1940)^(1/3) = 49/15

 

Eliminate the cube root on the left hand side.

Raise both sides to the power of three:

x - 1940 = 117649/3375

 

Solve for x.

Add 1940 to both sides:

x = 6665149/3375 = ~1975
