Помогите со степенями!(3 номер(в,г,д,е), как делать?

3. a ) 1/x =x^-1 и х^-1 =1/x

(6 =2*3, 6^4 =2^4*3^4)

6^-4 /2^-6*3^-4 =
=(2^6 *3^4) /(2^4 *3^4) =
=2² =4

в) (2^n*5^n)/10*10^n =
=10^n /10*10^n =1/10 =0.1

г)
24^n =(2²*6)^n=2^2n*6^n

(2^2n *6^n)/(2²*2^2n*6^n)=
=1/2² =1/4 =0.25

д) =(5²* 1 0^2n) /10^1n =5² =25

e)
(100^n *100) /((2^n/2)*25²*2 5^n =
=(10^2n *4*25)*2 /(2^2n *5^2n*25²) =
=(10^2n *4)*2 /(10^2n *25) =8/25 =0.32
