Correct. Just need to continue.
(32√3 + 8(3) + 196 + 49√3) / (16 - 3)
= (81√3 + 220) / 13
= 81/13 √3 + 220/13
b = 81/13 (or 6 3/13)
a = 220/13 (or 16 12/13)
(32√3 + 8(3) + 196 + 49√3) / (16 - 3)
= (81√3 + 220) / 13
= 81/13 √3 + 220/13
b = 81/13 (or 6 3/13)
a = 220/13 (or 16 12/13)
If you use calculator to check the answer you'll realise both give you the same result
i.e key in (8√3 + 49) ÷ (4 - √3) and compare this with 81/13 √3 + 220/13.
It will be the same.
OR
in one step, key in (8√3 + 49) / (4 - √3) - (81/13 √3 + 220/13)
Since both are supposed to be the same, the result should be 0.
