Find the value of k if frac k sqrt 3 sqrt 2 k s... - JAMB Mathematics 1998 Question

Find the value of k if \(\frac{k}{\sqrt{3} + \sqrt{2}}\) = k\(\sqrt{3 - 2}\)
A
3
B
2
C
\(\sqrt{3}\)
D
\(\sqrt 2\)
correct option: d

(\frac{k}{\sqrt{3} + \sqrt{2}}) = k(\sqrt{3 - 2})

(\frac{k}{\sqrt{3} + \sqrt{2}}) x (\frac{\sqrt{3} - \sqrt{2}}{\sqrt{3} - \sqrt{2}})

= k(\sqrt{3 - 2})

= k((\sqrt{3} - \sqrt{2}))

= k(\sqrt{3 - 2})

= k(\sqrt{3}) - k(\sqrt{2})

= k(\sqrt{3 - 2})

k2 = (\sqrt{2})

k = (\frac{2}{\sqrt{2}})

= (\sqrt{2})
