Question 188711
Note: type a set of triple curly braces around each individual term. So instead of typing [[[A=10 B=2]]], type [[[A=10]]] and [[[B=2]]] (imagine the square brackets are curly braces). So {{{A=10 B=2}}} then becomes {{{A=10}}} and {{{B=2}}}





{{{AB^2/(AB)^2}}} Start with the given expression.



{{{(10*2^2)/(10*2)^2}}} Plug in {{{A=10}}} and {{{B=2}}}



{{{(10*4)/(10*2)^2}}} Square 2 to get 4



{{{40/20^2}}} Multiply



{{{40/400}}} Square 20 to get 400



{{{1/10}}} Reduce



{{{AB^2/(AB)^2=1/10}}} when {{{A=10}}} and {{{B=2}}}
