√486 can be written as
√(2X3X3X3X3X3
so it can be written as 9√6
 \frac{9 \sqrt{6} }{2}  -  \sqrt{ \frac{27}{2} }  \\
 \frac{9 \sqrt{6} }{2}  -  \frac{3 \sqrt{3} }{ \sqrt{2} }  \\
  = \frac{9 \sqrt{6}  \sqrt{2}  - 6 \sqrt{3} }{2 \sqrt{2} }  \\  \frac{9 \sqrt{12} - 6 \sqrt{3}  }{2 \sqrt{2} }
 =  \frac{9 \times 2 \sqrt{3}  - 6 \sqrt{3} }{2 \sqrt{2} }  \\   =  \frac{18 \sqrt{3}  - 6 \sqrt{3} }{2 \sqrt{2} }
 =  \frac{12 \sqrt{3} }{2 \sqrt{2} }  \\   = \frac{6 \sqrt{3} }{ \sqrt{2} }
rationalize the denominator
 =  \frac{6 \sqrt{3}  \sqrt{2} }{ \sqrt{2} \sqrt{2}  }  \\  =  \frac{6 \sqrt{6} }{2}
 = 3 \sqrt{6}
is the final answer

we can write this question as 1/2 √2×3×3×3×3×3 - √ 27 /2
=1/2×3×3√2×3. - √3×3×3 /2
=1/2×3×3√2×3- 3√3/2
=3×3√1/4×2×3-. 3√3/2
=9√3/2 - 3√3/2
=√3/2. (9-3)
√3/2. ×6
so the answer is 6√3/2
