<PRE><B>Question 571740</B>
is there a short cut in solving the result of 125 cubed minus 125 squared. my grandson was in a math contest and someone solved the problem almost instantly.
How is that done?
-----------------------
{{{125^3 - 125^2 = 125^2*(125 - 1)}}}
= 15625*124
= 62500*31
--------------
Or
= {{{5^9 - 5^6 = 1953125 - 15625}}}
I could do it either way</PRE>
