Hi Liam. Exponential form usually means the exponential form of the prime factorization, written from smallest factor to largest.

For example, 4840 has the prime factorization 2x2x2x5x11x11, so we write it in exponential form like this:

2³ x 5¹ x 11²

Your large number will take awhile to discover the prime numbers. I will give you a hint though: it is the product of just two primes, occuring once each. This is like 91, whose expontial prime factorization form is 7¹ x 11¹.

Cheers,
