Question

write down the value of (5+√3)^2​

Answer 1

$\large{\underline{\underline{\mathfrak{\green{\bf{Solution:-}}}}}}$.

$\large{\underline{\underline{\mathfrak{\sf{Find\:here:-}}}}}$.

• $\:value\:of\:(5+\sqrt{3})^2$

$\large{\underline{\underline{\mathfrak{\green{\sf{Explanation:-}}}}}}$.

we know that ,

• $\large\boxed{\\:(x+y)^2\:=\:x^2+y^2+2xy}$

So,

$\implies\:(5+\sqrt{3})^2$

$\implies\:(5^2+\sqrt{3}^2+2×5×\sqrt{3}$

$\implies\:(25+3+10\sqrt{3}$

$\implies\boxed{\:(28+10\sqrt{3}}$

Answer 2

Answer:

45.3

Step-by-step explanation:

(5+root3)^2

(a+b) ^2 = a^2+b^2+2ab

=5^2+ root 3^2 + 2 x 5 x root 3

= 25 + 3 +10 root3

= 28 + 10 x 1.73

= 28 + 17.3

= 45.3
