Question

Exponents and logarithms and radical numbers...sooo simplify the expression nr.4

Answer 1

1)\[\frac{ 1 }{2-\sqrt{3} }\]
2)\[\frac{ 1 }{ 3+\sqrt{5} }\]

Answer 2

You need to find the conjugate and multiply the top and bottom by it.

Answer 3

The conjugate of \(a+\sqrt{b} \) is \(a-\sqrt{b}\)

Answer 4

and vice versa.

Answer 5

Can you do this for 1?

Answer 6

@ojeano I need cooperation here.

Answer 7

aby rat5ionalizing we get,
\[[2+\sqrt{3}]/[(2)^2-(\sqrt{3}^2)]\]

Answer 8

(2+root3)/(4-3)
=(2+root3)

Answer 9

similarly try to find out second one.
