✨Here is your solution ✌️⤵️⤵️

A = 7 -4√3

1/a = 1/( 7 -4√3) = (7-4√3)/(7-4√3)(7+4√3)

=(7+4√3)/(49-48) = (7+4√3)

so, √a = √( 7 -4√3)

= √(2²+√3²-2.2√3)

=√(2 -√3)² = ( 2 -√3)

same way ,

1/√a = √(2² +√3² +2.2√3)

=√(2+√3)²

=(2 +√3)

now ,

√a + 1/√a = (2 -√3) + (2 + √3) = 4

❤️❤️❤️Hope this will help you ✌️✨
