I don't see the radical you want simplified — could you paste it?
If you meant a general method, here it is briefly:
- For an nth root of an integer: factor the radicand into prime factors, group primes into bundles of size n, move each full bundle outside the radical, leave remainders inside. Example: √72 = √(36·2) = 6√2.
- For variables: for root index n, write each variable exponent as n·q + r. Move the variable to the outside with exponent q and leave exponent r inside. Example: √(x^4 y^3) = x^2 y√y (assuming x,y ≥ 0).
- For odd vs. even roots: odd roots can take negative radicands; even roots require nonnegative radicands (or use absolute values when taking principal even roots).
- To rationalize denominators: multiply numerator and denominator by an expression that makes the radical in the denominator a rational number (for √a multiply by √a, for higher roots use the appropriate conjugate).
If you post the specific radical, I’ll simplify it step by step.
