Question

Calculeaza (-81) la puterea a17a:(|12la puterea 99-3la puterea 66|)+8 la puterea 33 .
Macar sugestii va rog .

Answer 1

-  (-81)la putera a 17-a    = -3 la puterea 4·17= -(3)^68   

-    12^99=3^99·2^198           3^99·2^198- 3^66= 3^66(3^33·2^198-1)

-3^68÷3^66(3^33·2^198-1)=-3^2/(3^33·2^198-1)=-9/(3^33·2^198-1)

-   8^33=2^99

-9/(3^33·2^198-1) +2^99=([-9+ 3^33·2^297-2^99)]/(3^33·2^198-1)
