4096 is 212

The square root will be 26

The cube root will be 24

How to find the square root of 4096? It will be a two digit number.

Look at the last digit 6. This can be obtained only if the last digit of the root is 6 or 4.

Since the first two digit part of the given number is 40, it suggests that the first digit of the root is 6 (if you think it can be 5, 25 is too far from 40). So is the squaree root 66 or 64? Since 36 is closer to 40, then the root can be 64.

Check:

64; 6242 = 3616 + 2(6*4)*10 = 3616 + 480 = 4096

Thus, 642 = (26)2 = 212
