4√22/4√2*4√12/3√18

i got 450.27991294?

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. 
I got that doing ã(12/3) and ã(22/4)

4 square root 22 over 4square root 2 multiply by 4 square root 12 over 3 square root 18

then my answer should be right! :P

its called rationalizing the denominator

sorry its not rationalizing
