ベキ乗の指数を桁数に合わせるなら DIM n(11) MAT n = ZER INPUT keta IF keta<0 OR 10<keta THEN STOP LET n(keta) = 1 DO FOR i=1 TO keta+1 LET n(i) = n(i) + 1 IF n(i) >= 10 THEN LET n(i)=0 ELSE EXIT FOR NEXT i IF n(keta+1)<>0 THEN EXIT DO LET x = 0 LET y = 0 FOR i=1 TO keta LET x = x + n(i)^keta LET y = y + n(i)*(10^(i-1)) NEXT i IF x=y THEN FOR i=keta TO 2 STEP -1 PRINT "("; n(i); "^"; keta;") + "; NEXT i PRINT "("; n(1); "^"; keta; ") ="; x END IF LOOP END 昔のM$系ではループ処理がめどいので十進BASICでやった。
