Question

(√7+4)(√3+5) simplyfy​

Answer 1

Step-by-step explanation:

(4+√7)(3+√2)

→ 4(3+√2)+√7(3+√2)

→ 12+4√2+3√7+√14

Answer 2

Answer:

$(\sqrt{7} +4)(\sqrt{3} +5)$

       Using formula, $\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

$(\sqrt{7}\sqrt{3})+(\sqrt{7}\cdot \:5)+(4\sqrt{3})+(4\cdot \:5)$

$\sqrt{21}+5\sqrt{7}+4\sqrt{3}+20$
