$b = ( \frac{ \sqrt{50} }{2} + \frac{ \sqrt{18} }{3} - \frac{ \sqrt{2} }{2} + \frac{45}{5 \sqrt{2} } ) \div 4$

$b = ( \frac{ \sqrt{50} }{2} + \frac{ \sqrt{18} }{3} - \frac{ \sqrt{2} }{2} + \frac{9}{ \sqrt{2} } ) \div 4$

$b = ( \frac{5 \sqrt{2} }{2} + \frac{ \sqrt{18} }{3} - \frac{ \sqrt{2} }{2} + \frac{9}{ \sqrt{2} } ) \div 4$

$b = ( \frac{5 \sqrt{2} }{2} \div \frac{3 \sqrt{2} }{3} - \frac{ \sqrt{2} }{2} + \frac{9}{ \sqrt{2} } ) \div 4</p><p>$

$b = ( \frac{5 \sqrt{2} }{2} \div \frac{3 \sqrt{2} }{3} - \frac{ \sqrt{2} }{2} + \frac{9}{ \sqrt{2} } ) \times \frac{1}{4}$

$b = (\frac{5 \sqrt{2} }{2} + \sqrt{2} - \frac{ \sqrt{2} }{2} + \frac{9}{ \sqrt{2} } ) \times \frac{1}{4}$

$b = (3 \sqrt{2} + \frac{9}{ \sqrt{2} } ) \div \frac{1}{4}$

$b = \frac{15}{ \sqrt{2} } \times \frac{1}{4}$

$b = \frac{15}{4 \sqrt{2} }$

$b = \frac{15 \sqrt{2} }{8}$
