Question

(5+√3)² simplify this using formula ​

Answer 1

Step-by-step explanation:

=(5)²+(√3)²+2×5×√3

=25+3+10√3

=28+10√3

Answer 2

$(a+b)^{2}$= $a^{2}$ + $b^{2}$ + 2ab

Therefore,

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

               = 25 + 3 + 10$\sqrt{3}$

               = 28 + 10$\sqrt{3}$
