Answer:
3) C)
7) D)
Explanation for question 2)
Step 1:
4^3 = 64
4^4 = 256
4^9 = 262144
Step 2:
64 * 256 = 16,384
16,384/262,144 = 0.0625
Step 3:
0.0625 as a fraction, 1/16
-----------------------------------------------------
Now, we see there is no option as, 1/16
But, however there is 1/4^2 = 1/16
Because, 4^2 = 16
Therefore, 1/16
