potęgowanie .. mógłby mi ktoś to obliczyć? (-³₄)²= (1²₅)²= (¹₉)²= (0,02)²= (-17)²= (1,2)²= (0,3)²= (-³₄)³= (-⁷₈)²= (1,9)²=   z góry dzięki ;**

(-3/4)²=9/16 (1 2/5)²= (7/5)²=49/25=1 24/25 (1/9)²=1/81 (0,02)²=0,0004 (-17)²=289 (1,2)²=1,44 (0,3)²=0,09 (-3/4)³=-27/64 (-7/8)²=49/64 (1,9)²=3,61   w razie watpliwości pisz na PW
