Question

10-root18/root2 = a+broot2

Answer 1

Step-by-step explanation:

$\frac{10 - \sqrt{18} }{ \sqrt{2} } = a + b \sqrt{2}$

$\frac{10}{ \sqrt{2} } + \frac{ - \sqrt{18} }{ \sqrt{2} }$

$5 \sqrt{2} + ( \frac{ - \sqrt{18} }{ \sqrt{2} } ) \times \sqrt{2}$

$a = 5 \sqrt{2}$

$b = \frac{ - \sqrt{18} }{ \sqrt{2} }$
