Question

$3 \sqrt{27} \times 3 \sqrt{8 \time} \times 3 \sqrt{125 \: }$
​

Answer 1

Answer:

810√30

Step-by-step explanation:

$3 \sqrt{27} \times 3 \sqrt{8} \times 3 \sqrt{125} \\ = 3 \sqrt{3 \times 3 \times 3} \times 3 \sqrt{2 \times 2 \times 2} \times 3 \sqrt{5 \times 5 \times 5} \\ = 3 \times 3 \sqrt{3} \times 3 \times 2 \sqrt{2} \times 3 \times 5 \sqrt{5} \\ = 9 \sqrt{3} \times 6 \sqrt{2} \times 15 \sqrt{5} \\ = 9 \times 6 \times 15 \sqrt{3 \times 2 \times 5} \\ = 810 \sqrt{30}$
