Question

if a=4√5 find √a+1/√a​

Answer 1

Step-by-step explanation:

$\sqrt{a} + 1 \div \sqrt{a} \\ = (a + 1) \div \sqrt{a} \\ =( 4 \sqrt{5} + 1) \div \sqrt{4 \sqrt{5} } \\ =( 2 \sqrt{5} + 1 \div 2) \div \sqrt[4]{5}$

value of root 5 is 2.236 put this value and your answer will be

$(2 \times 2.236 + 0.5) \div \sqrt{2.236} \\ = 4.972 \div 1.5 \\ = 3.3146$
