Question

if root 5 + root 3 upon root 5 minus root 3 + root 15 be find the value of a and b ​

Answer 1

Step-by-step explanation:

$\sqrt{5} + \sqrt{3} \div \sqrt{5} - \sqrt{3} + \sqrt{15}$

$( \sqrt{5} + \sqrt{3} ) ^{2} - \sqrt{15} ( \sqrt{5} + \sqrt{3} )$

$8 + 2 \sqrt{15} - \sqrt{30} - 3 \sqrt{5} \div 5 - 3 - 15$

$\frac{8 + 2 \sqrt{15} - \sqrt{30 } - 3 \sqrt{5} }{ - 13}$
