1. Find the square root of 16.

The square root of 16 is 4

2. 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 (_)^2

Addition of 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 is 64.

64 is 8^2

3. Find square root : 7,225

The square root of 7225 is 85

4. Find cube root of 21,952 by prime factorization method.

prime factors of 21952 = 2x2x2x2x2x2x7x7x7

=> make three groups of same numbers

=> (2x2x2) x (2x2x2) x (7x7x7)

=> 2 x 2 x 7

=> 28

hence, 28^3 is 21952
