Question 775073
The property?, ... but I see  a way to take this.

{{{7(16/4^2)}}}
{{{7(4^2)/(4^2)}}}
{{{7*1}}}
{{{7}}}


You know already, {{{4*4=4^2=16}}}.  Finally, this is the multiplication property of 1.  
1 is the multiplication identity element for real numbers.  Maybe that was the property you were looking to find named.
