Answer 2

Answer:

4^4 = 2^8

8^8 = 2^24

6^6 = 2^6*3^6

so 2^40*3^6 as we already have 2^2

16^10/10 * 27^2/10

6 is the remainder and any power to 6 yeilds 6 in the units place also 7 is the remainder in the second part

so 6*9 as 9 is the units digit of 7^2 yeilds 54 hence 4 will be the units digit ...
