Question

(Root2-root3)(roota+root3)what is a

Answer 1

Answer:

The answer is =

a = 2

$\sqrt{a}$ = $\sqrt{2}$

Step-by-step explanation:

To find the value of a

Follow the identity

$(\sqrt{2} - \sqrt{3})(\sqrt{a} + \sqrt{3})$ = $(\sqrt{2})^{2} - (\sqrt{3})^{2}$

[Using identity $a^{2}$ - $b^{2}$ = (a + b)(a - b); here (a + b)(a - b) = $(\sqrt{2} - \sqrt{3})(\sqrt{a} + \sqrt{3})$]

So,

$\sqrt{a}$ = $\sqrt{2}$

And,

a = 2
