Question

4√3 − 5√7 + 2√3 + 6√7

Answer 1

Answer:

$\dashrightarrow \: { \tt{4 \sqrt{3} - 5 \sqrt{7} + 2 \sqrt{3} + 6 \sqrt{7} }} \\ \\ \dashrightarrow \: { \tt{(4 - 2) \sqrt{3} + (6 - 5) \sqrt{7} }} \\ \\ \dashrightarrow \: { \tt{2 \sqrt{3} + \sqrt{7} }} \\ \\ \dashrightarrow \: { \tt{ \sqrt{3 \times 4} + \sqrt{7} }} \\ \\ \dashrightarrow \: { \tt{ \sqrt{12} + \sqrt{7} }}$

Answer 2

Answer:

Step-by-step explanation:

$4\sqrt{3} - 5\sqrt{7} +2\sqrt{3} +6\sqrt{7}=4\sqrt{3} + 2\sqrt{3} -5\sqrt{7}+6\sqrt{7}$

                                        $=(4+2)\sqrt{3}+ (-5 +6)*\sqrt{7}\\\\=6\sqrt{3}+1\sqrt{7}$
