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
