Răspuns:

Explicație pas cu pas:

e) = (3/5)^20 : (3/5)^17 - 49/25 × 1/10 = (3/5)³ - 49/250 = 27/125 - 49/250 = (54-49)/250 = 5/250 = 1/50.

f) = (18/5)^63 : (18/5)^60 × 10/36 - 49/25 = =18^63/5^63 × 5^60/18^60 × 10/36 - 49/25 =

= 18³/5³ × 5/18 - 49/25 = 18²/5² - 49/25 = 324/25 -

- 49/25 = 275/25 = 11.
