We should change this as a project and an assignment.<br />Establish this property of numbers mathematically using two digit numbers.<br />While doing so pupils get the ablity to write number based on place values and viables as digits<br />say 10x + y is a two digit<br />Take fourth power<br />Pascal triangle can be introduced here<br />or suare of ( a+b) and suuaring again is possible<br />split the expansion as 10000( ) +4000( ) +600( ) +40 ( ) +1 ( )<br />take the digit sum<br />Complete the process sa in the second stage <br />we get same result easily.
