Question 1200167
?
??


Maybe something this way:
{{{(1*10^2+9*10^0)(1*10^2+9*10^0)}}}, and just perform the multiplication as if you would for binomials.


10 takes the place of a variable such as x.


{{{(10^2+9)(10^2+9)}}}

{{{(10^2)^2+9*10^2+9*10^2+9*9}}}

{{{10^4+18*10^2+9^2}}}

{{{10000+1800+81}}}

{{{11881}}}
