4√22/4√2*4√12/3√18

algebra 
Cody,
i got 450.27991294?

algebra 
Reiny,
confusion!
by 4√22/4....
so you mean
4(√22)/4... or 4√(22/4)...
same thing for the √12/3 part
if you mean √(12/3) that would be simply 2
or if you mean (√12)/3 then it is (2√3)/3
please clarify. 
algebra 
Cody,
I got that doing ã(12/3) and ã(22/4)
