18:05 4G+ 74% 20. Let L and M be intermediate fields in the extension KC F. (a) [LM: K] is finite if and only if [L: K] and [M: K] are finite. (b) If [LM: K] is finite, then [L: K] and [M: K] divide (LM: K] and [LM: K] [L: K][M: K]. (c) If [L: K] and [M: K] are finite and relatively prime, then [LM: K] = [L: KIM : K). (d) If L and M are algebraic over K, then so is LM.

18:05 74% 20. Let L and M be intermediate fields in the extension KCF. (a) [LM: K] is finite if and only if [L: K] and [MK] are finite. (b) If [LM: K] is finite, then [L: K] and [M: K] divide [LM: K] and [LM: K] [L: KIM: K]. (c) If [L: K] and [M: K] are finite and relatively prime, then [LM: K] [L: KI[M: K]. (d) If L and M are algebraic over K, then so is LM.
