Answer:
[tex] = 2 \sqrt{10} + 3 \sqrt{6} [/tex]
Step-by-step explanation:
[tex] \sqrt{5 \times 8} + 3 \sqrt{6} [/tex]
[tex] = \sqrt{40} + 3 \sqrt{6} [/tex]
[tex]but \: \sqrt{40} = \sqrt{20} \times \sqrt{2} [/tex]
[tex] = \sqrt{4} \times \sqrt{5} \times \sqrt{2} + 3 \sqrt{6} [/tex]
[tex]2 \times \sqrt{5} \times \sqrt{2} + 3 \sqrt{6} [/tex]
[tex] = 2 \sqrt{10} + 3 \sqrt{6} [/tex]
