rationalise 8/3root2-1​

Answer 1

Step-by-step explanation:

have ,

\mathtt{ \frac{17}{3 \sqrt{2} + 1 } to \: rationalise}

\frac{17}{3 \sqrt{2} + 1 } \times \frac{3 \sqrt{2} - 1 }{3 \sqrt{2} - 1}

\implies \frac{17(3 \sqrt{2} - 1) }{ {(3 \sqrt{2})}^{2} - {(1)}^{2} }

\implies \frac{17(3 \sqrt{2} - 1)}{18 - 1}

\implies 3 \sqrt{2} - 1
