Oblicz stosując prawa działań na potęgach
a. (0,8)⁴÷(⅖)⁴
b. 28⁴÷7⁴
c (10√2)³÷5³
a. (0,8)⁴÷(⅖)⁴=(4/5*5/2)⁴=2⁴=16
b. 28⁴÷7⁴=(28:7)⁴=4⁴=256
c (10√2)³÷5³=(10√2:5)³=(2√2)³=8*2√2=16√2
a)
(0,8)^4 :(2/5)^4 =(4/5 *5/2)^4 =2^4 =16
b)
28^4:7^4 =(28:7)^4 =4^4 =256
c)
(10V2)^3 :5^3 =(10V2:5)^3 =(2V2)^3 =8 *2V2 =16V2
