Sederhanakanlah √72 + √18 - √128

Sederhanakanlah √72 + √18 – √128

Jawaban:

$sqrt{2}$

Penjelasan dengan langkah-langkah:

$sqrt{72} = sqrt{36 times 2} = 6 sqrt{2}$

$sqrt{18 } = sqrt{9 times 2} = 3 sqrt{2}$

$sqrt{128} = sqrt{64 times 2} = 8 sqrt{2}$

Jadi

$6 sqrt{2 } + 3 sqrt{2} - 8 sqrt{2} = sqrt{2}$
