Question

Oblicz.

a) (1/2+2/3)do potęgi 2- 7/12

b) ( 1 2/3) do potęgi 2 x (3/5) do potęgi 3

c)6 do potęgi 2 x 2/9 (14: 2 1/3)

Answer 1

a) (1/2+2/3)do potęgi 2- 7/12 = (3/6 + 4/6)² - 7/12 = (7/6)² - 7/12 = 49/36 - 7/12 = 49/36 - 21/36 = 28/36 = 7/9

b)  ( 1 2/3) do potęgi  2 x (3/5) do potęgi 3 = (5/3)² * 27/125 = 25/9 * 27/125 = 3/5

c)6 do potęgi 2 x 2/9 (14: 2 1/3) = 36 * 2/9(14 : 7/3) = 8(14 * 3/7) = 8 * 6 = 48
