Respuesta :

Answer is 2/5 (√10 + √15)

Step-by-step explanation:

  • Step 1: To rationalize the denominator, multiply numerator and denominator by the conjugate of the denominator = (√8 + √3)

√5 (√8 + √3)/(√8 - √3)(√8 + √3) = (√40 + √15)/(8 - 3)

                                               [using the identity (a+b)(a-b) = a² - b²]

                                                      = 2/5 (√10 + √15)

Answer:

[tex]\frac{2\sqrt{10}+\sqrt{15} }{5}[/tex]

Step-by-step explanation:

[tex]\frac{\sqrt{5} }{\sqrt{8}-\sqrt{3} } =\frac{\sqrt{5}*(\sqrt{8}+\sqrt{3}) }{(\sqrt{8}-\sqrt{3})(\sqrt{8}+\sqrt{3}) } =\frac{\sqrt{40}+\sqrt{15} }{8-3} =\frac{2\sqrt{10}+\sqrt{15} }{5}[/tex]
