Answer:

$6 \sqrt{72} \: - \sqrt{18} \: - 8 \sqrt{32} \\ = \: 36 \sqrt{2} \: - 3 \sqrt{2} \: - 32 \sqrt{2} \\ = \sqrt{2}$

hope it's helpful

Answer 2

solution★

$= 6 \sqrt{2} - \sqrt{18} - 8 \sqrt{32}$

can this written as

$= 6 \sqrt{2 \times 3 \times 3 \times 2 \times 2} - \sqrt{2 \times 3 \times 3} - 8 \sqrt{2 \times 2 \times 2 \times 2 \times 2} \\ \\ = 6 \times 2 \times 3 \sqrt{2} - 3 \sqrt{2} - 8 \times 2\times2 \sqrt{2} \\ \\ = 36 \sqrt{2} - 3 \sqrt{2} - 32 \sqrt{2} \\ \\ = 36 \sqrt{2} - 35 \sqrt{2} \\ \\ = \sqrt{2} ans$

======================================

= >72=2×3×3×4

=>18=2×3×3

=>32=2×2×2×2×2
