SGC Maths Quest February 2019: Fly me to the moon SOLUTIONS

Here is the solution to the 'Fly me to the moon' Maths Quest February 2019:

Written as a product of prime numbers, 384,400 = 24x52x312

This can be written 22x22x52x312 or (2x2x5x31)2 which is a square number.

Therefore 384,400 is a square number. It is 6202.

There were correct entries received from 6 children as follows: 

Sophia Robinson, Emily Kondo, Lexie Cooke (all from Bishopsgate School), Thomas Farzaliyev (from Riverbridge Primary School) and Rafferty Stather and Luke Bicarregui (both from St George’s Junior School). An entry received from Monty Seager (from Bishopsgate School) was also highly commended.  

Congratulations to all of our winners and to all those who took part.
