Mathematics
1 answer:
Sauron [17]3 years ago
8 0

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} }
