The prime factorisation of 3825 is (a) `3\times 5^{2}\times21` (b) `3^{2}\times 5^{2}\times35` (c) `3^{2}\times 5^{2}\times3517` (d) `3^{2} 25 \times
The prime factorisation of 3825 is

(a) `3\times 5^{2}\times21`
(b) `3^{2}\times 5^{2}\times35`
(c) `3^{2}\times 5^{2}\times3517`
(d) `3^{2} 25 \times3517` 




(c) `3^{2}\times 5^{2}\times3517`

Explanation:
prime factorisation = 3825
3825 = 3 `\times`3 `\times`5 `\times`5 `\times`17 `\times`1

= `3^{2}\times 5^{2}\times 17`

So, the Correct answer is option is (c) `3^{2}\times 5^{2}\times3517`
