    9-4 = 5 ow im wrong 3^2 is not equal to 6 so its \[\sqrt{84} - \sqrt{16}\] I think its \[2\sqrt{21} + 4 \] I am not quite sure but it can be simplified the two will not exist and 4 will be 2

    \[\sqrt{81}+3^2-6-\sqrt{16}\]=9+9-6-4=8

    here is how its done. A ) 9, 27, 81 let 9=a , b=27 and c=81 the pythagorean theorem, a^2 + b^2 = c^2 so plug in the values and see if a^2 + b^2=c^2 .

    if this hold the you have the right answer. If not then try the B and c and D. THATS what i did and found out D IS the right answer
