Question

Sorry I keep asking, I'm not quite prepared for my math exam tomorrow and I was hoping y'all could help out a bit. thanks in advance!​

Answer 1

Answer:

$\frac{ \sqrt{18} }{5 \sqrt{18 } +3 \sqrt{4\times 18} -2 \sqrt{9 \times 18} }$

$\frac{1}{5 + 3 \sqrt{4} - 2 \sqrt{9} }$

$\frac{1}{5 + (3 \times 2) - (2 \times 3)}$

$\frac{1}{5 + 6 - 6}$

$\frac{1}{5}$
