## Exam-Style Question on Number## A mathematics exam-style question with a worked solution that can be revealed gradually |

Question id: 376. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.

The number, \(N\), can be written as the product of prime factors in index form as:

$$N = 3 × 5^3 × x^4$$Work out \(5N^2\) as a product of prime factors in index form giving your answer in terms of \(x\).
