Question

b) (33/50) la puterea 9 × (25/22) la puterea 9 d) (7/17) la puterea 5 : (21/17) la puterea 5 e) (13/8) la puterea 6 : (39/32) la puterea 6 ​

Answer 1

Răspuns:

b) (35/50)⁹×(25/22)⁹=

(7/10)⁹×(25/22)⁹=[(7×25)/(10×22)]⁹=

(35/44)⁹

d)(7/17)⁵:(21/17)⁵=(7/17)⁵×(17/21)⁵=

[(7×17)/(17×21)]⁵=(1/3)⁵

e)(13/8)⁶:(39/32)⁶=(13/8)⁶×(32/39)⁶=

[(13×32)/(8×39)]⁶=(4/3)⁶
