Write the prime factorization of the following numbers and hence find their square roots.(i) 7744 (ii) 9604 (iii) 5929 (iv) 7056

Answer»

(i) 7744 

7744 = 22 × 22 × 22 × 112

\(\sqrt{7744}\) = 2 x 2 x 2 x 11

= 88

(ii) 9604 

9604 = 22 × 72 × 72

\(\sqrt{9604}\) = 2 x 7 x 7

= 98

(iii) 5929 

5929 = 112 × 72

\(\sqrt{5929}\) = 112 x 72

= 77

(iv) 7056 

7056 = 22 × 22 × 72 × 32

\(\sqrt{7056}\) = 2 x 2 x 7 x 3

=84
