Heya,
Here's ur answer :-
The unit digit of 29 is 9
39 is an odd number.
When we take 9 to the power any odd number, the unit digit is always 9.
Ex:- 9^3 = 729, and 9 is the unit digit here.
So, now whatever value of 29^39 will come, the unit digit is 9.
Now we know that the new unit digit is 9.
And the new power is 45.
45 is again an odd number.
So, as proved above, the unit digit of whatever the value of 29^39^45 will come, it is 9.
So,overally, the final unit digit is 9.
