Explicație pas cu pas:
A)
(35/95)⁶ · (38/14)⁶ =
[(35:5)/(95:5)]⁶ · [(38:2) / (14:2)]⁶=
[(7/19) · (19/7)]⁶ =
1⁶ = 1
==================
B)
(33/50)⁹ · (25/22)⁹ =
[(33/22) · (25/50)]⁹ =
[(33:11)/(22:11) · (25:25)/(50:25)]⁹ =
(3/2 · 1/2)⁹ =
(3/4)⁹
==================
C)
(3/7)⁴ · (49/36)² =
(3⁴/7⁴) · (7²/6²)² =
(3⁴/7⁴) · (7⁴/6⁴) =
3⁴/6⁴ =
(3/6)⁴
