HEY MATE______________^^____^_

HERE IS IT ANSWER....☆☆☆☆☆☆☆

$\sqrt{400} = \sqrt{25 \times 16}$
$\sqrt{200} = \sqrt{100 \times 2}$
$\sqrt{160} = \sqrt{16 \times 10}$
$\sqrt{40} = \sqrt{10 \times 4}$
Now..
$\sqrt{400 } = 5 \times 4$
$\sqrt{160} = 4 \times \sqrt{10}$
$\sqrt{200} = 5 \times 2 \times \sqrt{2}$
$\sqrt{40} = 2 \times \sqrt{10}$

☆☆AGAIN,
MULTIPLING ALL♡♡
WE, GET
////___
$5 \times 4 \times 4 \times \sqrt{10} \times 10 \times \sqrt{2} \times 2 \times \sqrt{10}$
____
$16000 \times \sqrt{2}$
THANX...♡♡
